Matchroom, for practical purposes, had no decision to make in this situation.Matchroom was willing to enforce Billy’s ban for Mosconi Cup at WPA’s behest within the umbrella of WADA and IOC.

Billy, by playing in WPA Sanctioned events, was governed by WPA rules, which included compliance with WADA drug mandates. When Billy tested positive for a disallowed substance, he was in breach of his contract with WPA, and was disciplined for it by losing his eligibility to play in WPA-sanctioned events for a period prescribed by WPA. As a producer of several WPA-sanctioned events, Matchroom had no choice but to abide by WPA's decision.
