OPINION OF THE COURT
PER CURIAM:
The Court of Common Pleas of Butler County ruled that the Public Employe Relations Act of July 23, 1970, P.L. 563, 43 P.S. § 1101 et seq., was unconstitutional in so far as it provides for the right to strike by teachers. This ruling was improvident, Wiegand v. Wiegand, 461 Pa. 482, 337 A.2d 256 (1975), and is declared of no effect.
*22 Since the other issues posed by these appeals are now moot, the appeals are dismissed.
Each party to pay own costs.
