Under what circumstances is a match forfeited?

A match is forfeited when a team fails to meet the minimum requirements for player participation or does not comply with rules regarding conduct or timing. In this context, asserting that a match is not forfeited due to power failures or unforeseen circumstances reflects an understanding of the governing rules of volleyball, which typically allow for certain exceptions or the ability to reschedule matches in light of such events rather than immediately forfeiting.

Forfeiture is usually a result of a team being unable to field the required number of players or failing to adhere to match start times, rather than situations that are beyond anyone's control, such as power failures or unexpected incidents. Therefore, this answer aligns with the established regulations in volleyball, which aim to ensure fairness and competitive integrity.
