Judge to Connery: Cool it!

New York State Supreme Court Justice

Marcy Friedman

is sick and tired of a series of lawsuits and countersuits between

Sean Connery

and his Manhattan neighbor,

Burton Sultan,

over a years-long series of renovations that Connery, 77, has been making to his half of a six-story 1869 town house he and his wife share with the Sultan family.

Sultan, who says he is sick of the noise, fumes and other nuisances caused by the work, alleges in one of his suits that Connery is "a bully who ignores norms of neighborliness and decency."

Connery and his wife say Sultan's whining has delayed needed roof repairs.

Friedman has thrown out most of Sultan's claims, but also has chided the Connerys for their part in the ongoing dispute. She has barred both sides from filing any more lawsuits without her permission, saying they "have engaged in a 'slash-and-burn' litigation strategy."
