24 Pa. Stat. § 335
Whenever heretofore the school directors of any school district shall have taken any action, performed any duty or exercised any power, which by law required the affirmative vote of a majority, or greater proportion, of all the members of the board of school directors, and which by law was required to be recorded so as to show how each member of the board voted thereon--if such action or vote was actually taken, or duty performed, or power exercised by the board as required by law, the same shall be deemed and is hereby made valid and legal to all intents and purposes, notwithstanding the fact that the secretary of the school board, or the board, did not actually record on the minutes of the board the vote showing how each member voted, as required by law.
