“Therefore, an order was issued for suspension of Mrs. Shields’s boxing license, which was in force on the day of release. As a result, the Commission will place the name Mrs. Shields on the national suspension list or will notify the National Managers of the decision to suspend its license. “
The global boxing organization outlined procedures that should be performed to avoid losing the championships.
“The alleged criminal must” show the cause “, providing credible evidence of why the WBO World Championship Committee should not take affirmative actions in the delicate of alleged violations of regulations and/or WBO policy.
