They both have a valid case for a medal. Voinea's OOB could be argued as a field of play call that was impacted by viewing angle available.
Whereas the wrong call on Jordan's Gogean was simply wrong no matter what the angle. In which case, Barbosu is the Bronze medalist.
Personally, Voinea was overscored and shouldn't be in the conversation anyway, and Jordan should have been .1 less on execution than Barbosu (including Barbosu's OOB), so the call on the Gogean shouldn't matter.
Video review from multiple angles should be available for these calls, and E-judges should have video review as well.
