The legal row involving top players and the WPT over image rights has cranked up a notch with the news that the players have filed a motion with the courts in the US.

Seven of the world's leading professional poker players are seeking summary judgment against the World Poker Tour Enterprises in federal district court in Los Angeles.

In their motion for summary judgment, Chris Ferguson, Andrew Bloch, Annie Duke, Phil Gordon, Joseph Hachem, Howard Lederer, and Greg Raymer have presented undisputed facts which establish that WPTE, which owns the World Poker Tour, has committed multiple violations of federal antitrust laws.

The players, who are all massive figures within the global game, are after a declaration from the Court that WPTE and the casinos which host WPT events have unlawfully conspired to force poker players to sign non-negotiable "releases" that require those players to grant WPTE their image rights.
