Yes, it appears that the long-running TNA/WWE talent interference lawsuit is now over, with PWTorch reporting that America's No. 2 promotion filed the paperwork this past Monday to dismiss the lawsuit.
The lawsuit, which was announced in May of last year, stemmed from allegations by TNA that WWE used confidential contract information provided by ex-employee Brian Wittenstein to outsmart and outmaneuver them on various dealings (PWInsider wrote a lengthy and detailed report on the lawsuit here).
Notably, Ric Flair, whose name was specifically mentioned in the court documents, finally returned to WWE on Monday, apparently to begin a new program with The Miz and Antonio Cesaro. He had previously made a one-off guest appearance for the company at December's Slammy Awards.
No doubt Flair would have liked to return to the company a lot sooner, but as F4Wonline (h/t WrestlingInc) noted in October, WWE had sworn off signing him, feeling it would give the other side ample evidence against them to use in court.
Of course, the path still isn't totally clear. Flair is set to go off to Japan later this month, teaming with Keiji Mutoh to take on Tatsumi Fujinami and Seiya Sanada in an extremely high-profile match (via PWTorch).
Presumably, he'll be able to sign any deal he wants after that is finished. With his great track record as a draw, WWE will be eager to get him back. As CageSideSeats notes, his segment with Miz and Antonio Cesaro was, by far, the highest rated segment of the show, even beating Rock's concert and confrontation with CM Punk at the end.
Matt Morgan is another name that suffered due to the litigation. WrestlingInc noted that WWE was interested in Morgan after his TNA contract expired in the summer of last year, but the lawsuit forced them to hold off.
Morgan later returned to TNA.
Thankfully, with the lawsuit over, wrestlers in the U.S. looked to have regained their leverage once again.
