WORK, J.

Mel M. Marin appeals an order enjoining him from contacting any Scripps Health employee or coming within 500 yards of a Scripps facility or institution. (Code Civ. Proc., § 527.8) He challenges the issuance of the injunction on various grounds; however, we need only address his meritorious assertion the injunction violated public policy by being imposed under factual circumstances which did not establish a threat of future harm to the employees of Scripps Health. As we shall explain, in enacting section 527.8 the Legislature did not intend to alter the underlying nature and purpose of a prohibitory injunction and when such relief is accorded. Thus, to obtain a permanent injunction under section 527.8, subdivision (f), petitioner must establish not only defendant engaged in unlawful violence or made a credible threat of violence, but also that great or irreparable harm would result to employee without issuance of the prohibitory injunction. Because the record lacks any evidence that Marin posed a threat of future harm to any Scripps Health employee, we accordingly reverse the order.

FACTUAL AND PROCEDURAL BACKGROUND

In 1997, Marin's mother, Eva Marinkovic, was a patient at Green Hospital of Scripps Clinic, whose employees are employed by Scripps Health. After her cardiac surgery, her treating physicians informed Scripps she was stable and suitable for discharge. His sister, who was very concerned regarding the impending discharge of their mother from the hospital, contacted Marin. On behalf of his mother, he filed a power of attorney form for health care with the hospital and investigated the status of his mother's discharge. He filed a complaint with the Medical Review Board in Sacramento alleging the hospital was attempting to "dump" his mother from hospital. He noticed Nancy Quesnell, Director of Quality Resource Management/Risk Management, of his complaint. Both he and his father, Milivoy Marinkovic, objected to the discharge of Eva Marinkovic from the hospital.

On May 22, 1997, Marin and his father went to the hospital to drop off a copy of the complaint. Sheila Hale, a Scripps employee, contacted them and attempted to arrange a discussion regarding Eva Marinkovic's discharge plans. However, Marin was unable to do so, because he was on his way to court to be appointed guardian ad litem for his mother. He and his father returned later that afternoon and requested Hale for a meeting, advising her he intended to record the meeting. She advised Quesnell of their availability to meet, who in turn informed Marge Owens, Administrator of Medical/Legal Affairs for Scripps Clinic Medical Group. After a brief initial meeting, Owens, Quesnell, Marin and his father entered an empty patient room to conduct the meeting. The room contained a bed, two chairs and a bathroom, with only one access door at the end of a small entry hallway. Upon entering the room, Marin produced a tape recorder and repeated his intent to record the meeting. Quesnell told Marin she would not permit the meeting to be recorded. Marin put away his tape recorder and declared that they would take care of this in writing. He then started to walk out of the room. At that point, Owens closed the door to the room and stated, "We need to discuss your mother." She positioned herself between Marin and the door, rendering it impossible for him to leave the room. Marin responded that there was nothing to talk about and that he was going to open the door. Owens replied again, "We really need to discuss your mother." He then pulled the door open, striking Owens with the door and pushing her into the wall. Marin, visibly angered, left the hospital premises with his father. Owens and Quesnell notified security. Quesnell immediately announced she intended to get a restraining order against Marin.

On May 23, 1997, Scripps Health petitioned for an injunction to prohibit Marin from harassing its employees under section 527.8, alleging Marin had struck Owens with a door. Scripps Health concurrently applied for a temporary restrain order (TRO), ex parte, under that section, alleging Marin "may continue" to assault or batter an employee of Scripps Health. A TRO and an order to show cause re injunction were issued on May 23, with a hearing set for June 5. On May 27, Marin appeared ex parte and obtained an order vacating the TRO pending the order to show cause hearing. In doing so, the court relied on Marin's representation maintenance of the TRO could jeopardize his security clearance; however, the court conditioned the order on Marin's representation he would stay away from Scripps Health facilities pending the factual hearing. For the next two months, no restraining order was in effect and there were no acts or threats of violence by Marin at anytime during this period.

On July 24, the evidentiary hearing was held. Upon completion, counsel for Scripps Health argued the evidence supported a finding Marin had pushed Owens into the wall, slammed the door against her and then thrown his body into the door. He asserted an injunction was needed because Marin's past behavior, his allegations Scripps had failed to adequately care for his mother, and the threat he might cause harm to Scripps' employees if, in the future, anything happens to his mother that he relates to her release from the hospital. Scripps' counsel had earlier acknowledged that because Eva Marinkovic had her health insurance coverage transferred to the Sharp Healthcare, there is no reason for her to be patient at a Scripps Health facility except if she has an emergency. The court stated it found clear and convincing evidence that Marin "was the precipitating cause of an act of unlawful violence within the mean of . . . section 527.8" and "responsible for the injury to [Owens]." The court imposed a three-year permanent injunction against Marin precluding him from making contact with any employee of Scripps Health or to telephone or send any messages or communications to Scripps Health employees except through counsel or through an intermediary. The court further ordered Marin to remain 500 yards away from any Scripps facility or institution, unless he has a medical emergency and is taken to a Scripps facility. The court denied his request he be permitted to use the facilities at University of California at San Diego except for the library on the campus. The order was entered on October 30. Marin timely appealed.

THE INJUNCTION WAS IMPROPERLY ISSUED

Marin contends the injunction against him violates the codified public policy of imposing injunctive relief only where there is a threat of future harm to the petitioner, not as a remedy for a single past incident. Scripps Health responds by asserting that no showing of future harm is necessary as a finding of any past "unlawful violence" requires the issuance of an injunction under section 527.8, subdivision (f). It asserts that once the court finds by clear and convincing evidence a defendant was the precipitating cause of an act of unlawful violence within the meaning of section 527.8, subdivision (f), the petitioner is entitled to an injunction. (See 6 Witkin, Cal. Procedure (4th ed. 1997) Provisional Remedies, § 331, p. 264; 38 Cal.Jur.3d (rev.) Injunctions, § 45, p. 621.) However, as we shall explain, the Legislature did not intend in enacting section 527.8 to alter the underlying nature and purpose of a prohibitory injunction and when such relief is accorded. To obtain a permanent injunction under section 527.8, subdivision (e), a plaintiff must also establish great or irreparable harm would result to an employee without issuance of the prohibitory injunction because of the reasonable probability the wrongful acts will be repeated in the future.

More specifically, Scripps Health asserts the language in section 527.8, subdivision (f) is clear that once the court finds by clear and convincing evidence the defendant engaged in unlawful violence or made a credible threat of violence, "an injunction shall issue prohibiting further unlawful violence or threats of violence." It argues this language removes from the court any discretion to deny the relief requested. It contrasts this language to that of section 527.8, subdivision (e), which provides the plaintiff "may obtain" a TRO if it shows "to the satisfaction of the court" reasonable proof of unlawful violence and a threat of great or irreparable harm. Scripps Health thus argues that the Legislature intended to leave the determination of whether to grant or deny a TRO to the discretion of the trial court, but not so as to the issuance of a permanent injunction. (See § 527.8, subd. (f).) In summary, according to Scripps Health, to obtain temporary injunctive relief before the hearing under section 527.8, subdivision (e), a petitioner must show defendant committed an act of unlawful violence and a threat of great or irreparable harm; but, to obtain a permanent injunction after a full hearing, the plaintiff must show by clear and convincing evidence defendant engaged in unlawful violence or made a credible threat of violence. Consequently, Scripps Health asserts that under the plain language of the statute, no separate showing of a threat of future harm is required in order to obtain a permanent injunction.

Preliminarily, where the statutory language in dispute is clear and unambiguous, there is no need for construction and the judiciary should not indulge in it. ( California Fed. Savings Loan Assn. v. City of Los Angeles (1995) 11 Cal.4th 342, 349.) However, if the statutory language is not so clear, "[i]t is our task to construe, not to amend, the statute." ( Ibid.) In construing a statute, it is the role of the judiciary to simply ascertain and declare what is in terms or in substance contained in the statute, not to insert what has been omitted or omit what has been included. In other words, the courts "may not, under the guise of construction, rewrite the law or give the words an effect different from the plain and direct import of the terms used." ( Ibid.)

Where we must construe a statutory provision, we are guided by the firmly established principles governing statutory interpretation: "`The fundamental purpose of statutory construction is to ascertain the intent of the lawmakers so as to effectuate the purpose of the law. [Citations.] In order to determine this intent, we begin by examining the language of the statute. [Citations.] But "[i]t is a settled principle of statutory interpretation that language of a statute should not be given a literal meaning if doing so would result in absurd consequences which the Legislature did not intend." [Citations.] Thus, "[t]he intent prevails over the letter, and the letter will, if possible, be so read so as to conform to the spirit of the act." [Citation.] Finally, we do not construe statutes in isolation, but rather read every statute "with reference to the entire scheme of law of which it is part so that the whole may be harmonized and retain effectiveness." [Citation.]'" ( People v. Ledesma (1997) 16 Cal.4th 90, 95, quoting People v. Pieters (1991) 52 Cal.3d 894, 898-899.)

We grant that at first glance the express language of section 527.8, subdivision (f) appears to provide that once the trial court finds by clear and convincing evidence defendant has engaged in an act of unlawful violence a permanent injunction shall issue prohibiting further unlawful violence. However, a closer look at the subdivision within the context of the entire statute, its underlying legislative intent and the nature of injunctive relief, persuades us such a literal interpretation cannot be given to the disputed statutory language. Indeed, by harmonizing that subdivision with the remainder of section 527.8, it becomes evident that before an injunction shall issue the court must find by clear and convincing evidence to not issue the injunction would subject the targeted employee to great or irreparable harm, or in other words further unlawful violence or threat thereof.

Preliminarily, the express codified purpose of a prohibitory injunction is to prevent future harm to the applicant by ordering the defendant to refrain from doing a particular act. (Civ. Code, § 3420; § 525) Consequently, injunctive relief lies only to prevent threatened injury and has no application to wrongs that have been completed. ( Gold v. Los Angeles Democratic League (1975) 49 Cal.App.3d 365, 372.) It should neither serve as punishment for past acts, nor be exercised in the absence of any evidence establishing the reasonable probability the acts will be repeated in the future. Indeed, a change in circumstances at the time of the hearing, rendering injunctive relief moot or unnecessary, justifies denial of the request. ( Cisneros v. U.D. Registry, Inc. (1995) 39 Cal.App.4th 548, 574; Donald v. Cafe Royal, Inc. (1990) 218 Cal.App.3d 168, 184.) Moreover, not only can injunctive relief be denied where the defendant has voluntarily discontinued the wrongful conduct ( Cisneros v. U.D. Registry, Inc., supra, 39 Cal.App.4th at p. 574), there exists no equitable reason for ordering it where the defendant has in good faith discontinued the proscribed conduct ( People v. National Association of Realtors (1981) 120 Cal.App.3d 459, 476). "Thus, to authorize the issuance of an injunction, it must appear with reasonable certainty that the wrongful acts will be continued or repeated." ( Gold v. Los Angeles Democratic League, supra, 49 Cal.App.3d at p. 372.)

The Legislature has declared the availability of injunctive relief in particular situations in a series of statutes (see 6 Witkin, Cal. Procedure, supra, Provisional Remedies, § 293, pp. 233-234), such as where there is a threat of waste or injury to public funds or property (§ 526a), where there is a threat of interference with collective bargaining activities (§ 527.3) or where there is a threat of harm due to harassment (§ 527.6), group violence (§ 527.7) or violence towards employees at the workplace (§ 527.8). At the time section 527.8 was enacted, section 527.6 prevented harassment when there has been a knowing and willful course of conduct directed at a specific person which annoys or harasses the person and serves no legitimate purpose. The reasonable construction of this harassment provision required the applicant to establish a course of conduct giving rise to a threat of future harm necessitating injunctive relief. In other words, the course of conduct must be ongoing at the time the injunction is sought, as a single incident of harassment does not constitute a course of conduct entitling the applicant to injunctive relief. ( Leydon v. Alexander (1989) 212 Cal.App.3d 1, 4.)

Section 527.8 was enacted in 1994 to establish parallel provisions to section 527.6. It authorized any employer to pursue a TRO and an injunction on behalf of its employees to prevent threats or acts of violence by either another employee or third person. Given that section 527.6 only allowed injunctive relief for natural persons (see Diamond View Limited v. Herz (1986) 180 Cal.App.3d 612, 618-619), section 527.8 was enacted to allow a corporate employer to bring such an action on behalf of an employee. Section 527.8 was thus intended to enable employers to seek the same remedy as section 527.6 provides for its employees. The express intent of the author of the legislation was to address the growing phenomenon in California of workplace violence by providing employers with injunctive relief so as to prevent such acts of workplace violence. (Sen. Rules Com., 3d reading analysis of Assem. Bill No. 68 (1993-1994 Reg. Sess.), Aug. 31, 1994; Assem. Bill No. 68, Conc. in Sen. Amends. (1993-1994 Reg. Sess.), Aug. 31, 1994; Sen. Com. on Judiciary, Analysis of Assem. Bill No. 68 (1993-1994 Reg. Sess.) as amended June 30, 1994.)

Consistent with the foregoing, section 527.8, subdivision (a) expressly declares the Legislature's intent to provide employers with traditional prohibitory injunctive relief on behalf of their employees who have suffered unlawful violence or a credible threat of such violence from facing more in the future. Section 527.8, subdivision (a) states: "Any employer, whose employee has suffered unlawful violence or a credible threat of violence from any individual, which can reasonably be construed to be carried out or to have been carried out at the workplace, may seek a temporary restraining order and an injunction on behalf of the employee prohibiting further unlawful violence or threats of violence by that individual." As summarized earlier, section 527.8, subdivision (e) provides that plaintiff may obtain a TRO if it files an affidavit establishing reasonable proof an employee has suffered unlawful violence or a credible threat of violence by defendant and that great or irreparable harm would result to an employee. This latter requirement requires plaintiff to show to the satisfaction of the court it is likely that harm will occur from future unlawful violence in the absence of a restraining order. The parties do not dispute this interpretation of section 527.8, subdivision (e), as it is consistent with the express language of section 527.8, subdivision (a) and the cited underlying legislative intent.

In this light, to read literally the language of section 527.8, subdivision (f) would result in the absurd consequence of placing a greater burden of proof on plaintiff to obtain an ex parte TRO than a permanent injunction. A TRO, like a preliminary injunction, is by design to preserve the status quo pending the evidentiary hearing to determine whether to issue a permanent injunction. ( California State University, Hayward v. National Collegiate Athletic Assn. (1975) 47 Cal.App.3d 533, 543.) Scripps Health would have us read section 527.8, subdivision (f) in a vacuum, relying on the literal meaning of the language that once the court finds by clear and convincing evidence a defendant engaged in unlawful violence then a permanent injunction must issue, while ignoring the requirement under section 527.8, subdivision (e) that for a TRO to issue plaintiff must show great or irreparable harm would result to the employee due to the likelihood the unlawful violence will recur. Common sense does not permit us to do so. Indeed, the Legislature attached the same interpretation we do to the language in dispute, declaring "[a]n injunction shall issue if the judge is persuaded, by clear and convincing evidence, that violence, or the threat of violence, exists." (Assem. Bill No. 68, Conc. in Sen. Amends. (1993-1994 Reg. Sess.), Aug. 31, 1994, p. 2.) In other words, at the time of the hearing a plaintiff must show unlawful violence or threats of violence exist requiring the issuance of a prohibitory injunction.

Our review of the underlying legislative history and documents relevant to the enactment of section 527.8 has disclosed no evidence of a legislative intent to alter the traditional nature of prohibitory injunctive relief in this setting. Rather, it is quite clear the Legislature intended to provide employers with the remedy of injunctive relief to protect their employees by preventing unlawful violence where it is reasonably likely such unlawful violence may occur in the future. Accordingly, to obtain a permanent injunction under section 527.8, subdivision (f), a plaintiff must establish by clear and convincing evidence not only that a defendant engaged in unlawful violence or made credible threats of violence, but also that great or irreparable harm would result to an employee if a prohibitory injunction were not issued due to the reasonable probability unlawful violence will occur in the future.

THE RECORD LACKS SUBSTANTIAL EVIDENCE MARIN IS LIKELY TO COMMIT FURTHER ACTS OF VIOLENCE AGAINST ANY SCRIPPS HEALTH EMPLOYEE

At the outset of the evidentiary hearing, counsel for Scripps Health acknowledged there had been no prior threats of violence or any subsequent threats of violence by Marin against any employees of Scripps Health and that they were there only because of the alleged assault and battery upon Owens. The TRO was vacated four days after its issuance on Marin's express representation he would stay away from Scripps Health facilities pending the evidentiary hearing, leaving him unrestrained during the approximately two months before the evidentiary hearing. During this time, Scripps Health acknowledged Marin's mother again was taken to a Scripps facility and remained overnight before being discharged. Marin made no threats of violence or caused any violence while his mother was a patient at the facility. Thereafter, his mother transferred her health insurance to Sharp Healthcare, rendering it unlikely she would have to return as a patient to a Scripps facility. Consequently, given the circumstances surrounding this single incident, the evidentiary record does not establish the likelihood Marin would repeat any violent acts against Scripps Health employees. Accordingly, the order granting the permanent injunction must be reversed.
