2024 Olympics
At the 2024 Olympic Games Voinea helped Romania finish seventh in the team competition. Individually she qualified to the balance beam and floor exercise event finals. During the balance beam final she fell off the apparatus twice and finished eighth.[11] During the floor exercise final Voinea scored a 13.700 and initially finished in fourth place after losing an execution score tie-breaker with compatriot Ana Bărbosu. However, American Jordan Chiles submitted an inquiry on her score, initially a 13.666, which was accepted and raised her score by a tenth to 13.766. As a result Chiles was initially awarded the bronze medal, with Bărbosu in fourth, and Voinea in fifth.[12]
During the NBC primetime replay of the event final, it showed that Voinea did not go out of bounds despite receiving a neutral deduction of 0.1 for going out of bounds. If the deduction was not taken, Voinea would have scored 13.800, which would have put her in the bronze medal position even after Chiles's score was increased.[13] The Romanian Gymnastics Federation appealed this deduction simultaneously while appealing that Chiles' inquiry was submitted after the 1 minute deadline to the Court of Arbitration for Sport (CAS).[14] Voinea's appeal was rejected as her coach did not submit an inquiry about the neutral deduction during the event final.[15]
Bărbosu's appeal, however, was accepted as the CAS found that Chiles' inquiry was submitted four seconds past the one minute deadline. Therefore the FIG reinstated the original standings, which led to Bărbosu placing third, Voinea placing fourth, and Chiles placing fifth.[16] The International Olympic Committee upheld the findings from the CAS.[17]
