Is it true or false that lifters can challenge referees' decisions to the jury on a competitor's lift?

Lifters cannot challenge referees' decisions regarding their lifts to the jury, which is why the answer is false. In powerlifting, referees are appointed to judge the competition based on recognized rules and standards. Their decisions on whether a lift meets the criteria are final and are not subject to appeal or challenge by the lifters.

This system ensures that the competition runs smoothly and maintains the integrity of the judging process. The authority of the referees is an essential aspect of the sport, as it guarantees that all lifts are judged fairly and consistently according to the established rules. Therefore, lifting challenges against referees' decisions would disrupt the orderly conduct of competition and could lead to confusion or disputes that undermine the spirit of the event.

The other options, such as whether challenges depend on the type of lift or are only applicable to international competitions, do not apply because the rules about the finality of referee decisions are consistent across all types of lifts and competitions, both local and international.
