What is the minimum number of referees required to validate a lift in powerlifting?

In powerlifting, the minimum number of referees required to validate a lift is three. This practice ensures a fair and accurate assessment of the lifter's performance and helps to minimize bias or mistakes in judgment. Each referee is expected to evaluate the lift independently based on the specific criteria outlined in the rules, which include correct technique and adherence to the sport's standards.

Having three referees also allows for a majority decision, which is crucial in the event of disagreements on whether a lift has been successful or not. This system upholds the integrity of the competition by ensuring that all calls are made collectively and with oversight. It's a safeguard to maintain fairness for all competitors, as it balances any potential subjective opinions a single referee might have.
