Wilbur Ross will have to leave his former partner’s money alone.

A Manhattan judge ruled Thursday that the billionaire investor needed to put $1.7 million that his former partner David Storper earned in commissions from his funds in escrow pending a July 12 hearing.

Storper and Ross are suing each other in a separate case, and Storper had asked the judge to stop Ross from holding his commissions, which he allegedly did on May 11 and June 3.

In 2012, Storper left WL Ross & Co. after having been considered a possible Ross successor.

Meanwhile, Ross on Wednesday won a hard-fought shareholder vote to keep his listed vehicle, WL Ross Holding, operating. Shareholders approved the $1.6 billion acquisition of Nexeo Solutions only days before a deadline that would have forced it to liquidate.
