SHEPARD, Chief Justice.

This is an appeal from a judgment of conviction of the infamous crime against nature and the imposition of sentence. The sole questions presented are whether the statute is unconstitutionally void and ambiguous and whether the trial court erred in sentencing the defendants. We affirm the convictions and sentences.

The defendants were charged with having committed an infamous crime against nature, a violation of I.C. § 18-6605, which provides:

"Crime against nature — Punishment. — Every person who is guilty of the infamous crime against nature, committed with mankind or with any animal, is punishable by imprisonment in the state prison not less than five years."

Following their entry of an initial plea of not guilty, the defendants moved to withdraw their pleas and enter a demurrer to the information on the ground that the subject statute was unconstitutionally vague and ambiguous. That motion was denied. Following a trial by jury the defendants were convicted and each was sentenced and committed for a prison term of not to exceed ten years.

We consider first the appellants' argument that the statute is void for vagueness. The United States Supreme Court has stated:

"Void for vagueness simply means that criminal responsibility should not attach where one could not reasonably understand that his contemplated conduct is proscribed." United States v. National Dairy Products Corp., 372 U.S. 29 (1963).

See also Grayned v. City of Rockford, 408 U.S. 104, 92 S.Ct. 2294, 33 L.Ed.2d 222, 83 S.Ct. 594, 9 L.Ed.2d 561 (1972), and Smith v. Goguen, 42 U.S.L.W. 4393, — U.S. — , 94 S.Ct. 1242, 39 L.Ed.2d 605 (1974). It is also stated that reference should be made to any authoritative judicial construction of the statute. Winters v. People of State of New York, 333 U.S. 507, 68 S.Ct. 665, 92 L.Ed. 840 (1948); State v. Crawford, 478 S.W.2d 314 (Mo. 1972), appeal dismissed 409 U.S. 811, 93 S.Ct. 176, 34 L.Ed.2d 66 (1972).

We deem it clear that there has been authoritative judicial construction of this particular statute in this state and that such has been uniform for 58 years. In the case of State v. Altwatter, 29 Idaho 107, 157 P. 256 (1916) this court specifically held that the statutory crime against nature might be committed "per os." That determination was followed in the decisions of State v. Wall, 73 Idaho 142, 248 P.2d 222 (1952) and State v. Larsen, 81 Idaho 90, 337 P.2d 1 (1959), cert. denied 361 U.S. 882, 80 S.Ct. 154, 4 L.Ed.2d 119 (1959). Common to most if not all vagueness cases is the principle that the words of the questioned statute should not be evaluated in the abstract but should be considered with reference to the particular conduct of the defendants. United States v. National Dairy Products Corp., 372 U.S. 29, 83 S.Ct. 594, 9 L.Ed.2d 561 (1963); Smith v. Goguen, supra (White, J., concurring in the judgment).

We are therefore required to consider the facts giving rise to this action. All of the defendants herein were prison inmates at the time of this incident, which occurred within the walls of the Idaho State Penitentiary. The victim was a 19 year old man who had been committed to the penitentiary under a 120 day retention of jurisdiction (I.C. § 19-2601). Some weeks after his commitment, the victim in the evening hours was persuaded by several other inmates to enter the prison chapel for the alleged purpose of playing the piano. After briefly playing the piano, the victim was seized, dragged to the stage, repeatedly beaten, struck, kicked and threatened with death. In the presence of approximately twelve other inmates and while the victim was being further beaten he was forced to perform the act of fellatio upon several of the inmates there present, the four defendants among them. While he was being forced to commit those acts, the victim was also entered anally.

It is beyond doubt that the defendant's acts fall squarely within the very core of I.C. § 18-6605 as uniformly construed for 58 years. State v. Altwatter, supra; State v. Wall, supra; State v. Larsen, supra.

Appellants cite only in support of their void for vagueness argument the cases of Franklin v. State, 257 So.2d 21 (Fla. 1971), and Harris v. State, 457 P.2d 638 (Alaska 1969). We believe Franklin to be clearly distinguishable from the case at bar. Therein two consenting adults "committing a crime against nature" in a secluded area were apprehended by a police officer. Upon conviction the Florida Supreme Court reversed the judgment of conviction of a felony and remanded the cases for sentencing as misdemeanors in accordance with a statute which read:

"Whoever commits any unnatural and lascivious act with another person [shall be punished as a misdemeanor]."

In Harris, the Alaska court pointed out that the term "crime against nature" had at that time never been authoritatively judicially construed in Alaska. Therein the court went on in a monumental opinion to find Alaska's statute void for vagueness. Nevertheless the case was remanded to the trial court for entry of an amended judgment "reflecting a conviction for the crime of sodomy and not a crime against nature." 457 P.2d at 649.

As heretofore stated both Harris and Franklin are clearly distinguishable from the case at bar. We find the void for vagueness argument of the appellants to be without merit.

The appellants also argue that the sentence imposed by the trial court was erroneous. They contend that I.C. § 18-6605 does not specify a maximum sentence and further argue that since the enactment of I.C. § 19-2513 (the indeterminate sentence statute) no minimum sentence is prescribed. The defendants argue therefrom that they should have been sentenced under the provisions of I.C. § 18-112, which provides:

"Punishment for felony. — Except in cases where a different punishment is prescribed by this code, every offense declared to be a felony, is punishable by imprisonment in the state prison not exceeding five years, or by fine not exceeding $5,000, or by both such fine and imprisonment."

The argument of the defendant has been previously disposed of by this court in the decision In re Miller, 23 Idaho 403, 129 P. 1075 (1913). In Miller the defendant, who was also convicted of having committed the crime against nature, was sentenced to 25 years imprisonment. In Miller it was also argued that the maximum punishment for the crime was fixed at five years, citing [R.C. § 6312] I.C. § 18-112. That contention was rejected in Miller, wherein the court stated:

"Under the provisions of said section 6810, the term of imprisonment fixed is not less than five years and the maximum is left to the discretion of the court, hence that section prescribes the punishment for said offense, and since both the maximum and minimum sentences are in fact provided for by section 6810, the minimum being expressly fixed and the maximum left to the discretion of the court, it does not come within the provisions of section 6312, as it applies only to offenses where no punishment whatever is prescribed." (Emphasis supplied) 23 Idaho at 405, 129 P. at 1075.

Judgment of the trial court is affirmed.
