While Vijay Singh was setting out for his second round at the Masters on Friday, his lawsuit against the PGA Tour took another turn in the New York Supreme Court.

Singh’s attorneys requested the court intervene in what promises to be a spirited discovery phase of the trail, asking Justice Eileen Bransten to compel the Tour to produce documents “it will ultimately be obligated to provide,” wrote Singh’s attorney Peter Ginsberg.

On March 5 the court ordered a confidentiality agreement that was agreed to by both parties, but the Tour has refused to provide the requested documents until a pending motion is resolved.

“The apparent rationalization for the PGA Tour’s refusal to abide by its discovery obligations is that it wants to make one, and not an additional, production,” wrote Ginsberg in a letter dated April 11.

“The PGA Tour has no legal justification for its continuing refusal to produce indisputably relevant documents and information within the (Tour’s) custody and control which do not fall within the scope of the pending motion to compel.”

According to the letter, the Tour produced 1,018 pages of documents that consisted “almost entirely of publicly-available documents.”

Ginsberg’s letter requests a conference to resolve the matter.

Singh sued the Tour last May following an apparent violation of the Tour’s anti-doping program after he admitted to using a substance, IGF-1, that is banned by the policy. The Tour later reversed that ruling and absolved Singh of any wrongdoing.

The Tour does not comment on ongoing litigation.
