A federal appeals court has upheld a ruling that allows a San Jose State women’s volleyball team member to play in the Mountain West Conference tournament after complaints said she should be ineligible on grounds that she’s transgender.

The plaintiffs sued the Mountain West and its commissioner over the participation of a player who they say is transgender.

Twice during the regular season, the Boise State women’s volleyball team took a moral stand by forfeiting matches against San Jose State rather than competing against a player believed to be transgender.
