Resolving an 11-year legal saga under New York law, the Delaware Supreme Court on Monday ruled that two manufacturers of industrial pumps may seek excess insurance coverage for any asbestos injuries that occurred during insurers’ policy periods.

In so ruling, the high court rejected a Superior Court’s ruling that limited Viking Pump Inc. and Warren Pumps to recover under insurance policies in effect when the underlying plaintiffs first encountered the dangerous mineral, a proposition that has come to be known as the so-called “exposure trigger.”
