NBA players rejected the league’s latest offer Monday and began disbanding the union, likely jeopardizing the season.

“We’re prepared to file this antitrust action against the NBA,” union executive director Billy Hunter said. “That’s the best situation where players can get their due process.”

He said players were not prepared to accept the NBA Commissioner David Stern’s ultimatum, saying they thought it was “extremely unfair.”

Stern had urged players to take the deal on the table, saying it’s the best the NBA can offer and warned that decertification is not a winning strategy.

“This is the best decision for the players,” union president Derek Fisher said. “I want to reiterate that point, that a lot of individual players have a lot of things personally at stake in terms of their careers and where they stand. And right now they feel it’s important — we all feel it’s important to all our players, not just the ones in this room, but our entire group — that we not only try to get a deal done for today but for the body of NBA players that will come into this league over the next decade and beyond.”

Fisher, flanked at a press conference by dozens of players including Kobe Bryant and Carmelo Anthony, said the decision was unanimous.
