Substitution of parties does not affect the right to use depositions previously taken; and when there are pending in the same court several actions or suits between the same parties, depending upon the same facts, or involving the same matter of controversy, in whole or in part, a deposition taken in one of such actions or suits, upon notice to the same party or parties, may be read in all, so far as it is applicable and relevant to the issue; and, when an action in any court of the United States or of this or any other state has been dismissed and another action involving the same subject matter is afterward brought between the same parties or their representatives or successors in interest, all depositions lawfully taken and duly filed in the one action may be used in the other as if originally taken therefor.
