Billionaire Alex Sapir and partner Rotem Rosen finally succeeded on Monday in getting Jason Kalisman to check out of the Mondrian SoHo.

A Manhattan judge ruled that Sapir and Rosen’s ASRR Capital had the right to break the long-term deal Kalisman’s Morgans Hotel Group had to manage the Mondrian.

ASRR and Morgan had been fighting over management of the flashy downtown hotel since Sapir bought the 263-room operation out of foreclosure — with Kalisman claiming unsuccessfully that the contract couldn’t be broken.

The spat climaxed in the wee hours of April 6 when Kalisman’s team called the cops after ASRR management showed up to take over management of the 9 Crosby Street building.

While Sapir lost that first round — Justice Lawrence Marks ruled Monday morning that Sapir did have the right to break the deal — and could manage the hotel.

Both sides need to submit a plan for the orderly transition to take place before May 1, Bruce Kaplan, of Friedman Kaplan Seiler & Adelman, Sapir’s lawyer, told The Post.

Sapir’s publicly traded Israeli company ASRR bought the celebrity magnet hotel March 6 for $205 million out of foreclosure.

“We want to succeed or fail on our own abilities and with our own management team,” Kaplan said.

Sapir plans to make offers to all of the more than 200 Mondrian SoHo employees to remain — except for the hotel manager. ASRR plans to rename the hotel the NoMo Soho.

Justice Marks did not rule on Morgans claim that it is owed a $110 million fee because of a long-term management contract — one that paid it $2.5 million a year.

“While we are disappointed in the court’s decision to order a transfer of operations at Mondrian SoHo, we will continue to pursue our damages claim [against Sapir] for willful breach of our management contract,” a Morgans spokesman said.
