correcting an error

[Don1415]

Recent High School varsity game, umpire incorrectly stopped the game after 8 innings, tied score, saying that HS Federation rules specify "no new inning after 2 1/2 hours." Is there a procedure / process or are there rules governing what the status of this game is? Must it be resumed / replayed / not considered for league record / other? If one team wants to resume, the other doesn't, is that a forfeit? Is there a "controlling authority" somewhere?

Thanks.
