In a T2 playoff match, my friend and her partner were up 6-2, 5-3. One of the opponents' husband and three small children (ages about 3, 5, and 9) were watching the match from the car. Late in the evening, after dark, my friend is about to serve for the match when all three kids walk all the way around the courts to the other side where the light switch is, turn off the lights, giggle and run back to their daddy waiting in the car. Dad cranks it up and they take off. Needless to say, my friends were pretty upset. They got no apology, nothing. They had to wait 15-20 minutes for the lights to come back on before continuing play. Thankfully she held her serve. Could they have claimed the match when the lights went out?!? USTA rules are followed by this league.
