This week, art dealer Larry Gagosian asked New York State Supreme Court to throw out the lawsuit collector Ronald Perelman filed against him last fall.  Gagosian and Perelman have been embroiled in a debate over the sale of a Jeff Koons sculpture, with Perelman claiming that Gagosian used his position to take advantage of Perelman in the sale.  “I really think that these two gentlemen ought to get together at a cocktail party in the Hamptons this summer,” Justice Barbara Kapnick said. “This is a crazy case to have going on in this court and you ought to see if this can’t get resolved before I write a decision.”
