Piacquadio v Recine, 84 NY2d 967
Bill set legal precedent for slip and fall cases in New York when he obtained a reversal of the intermediate appellate court by New York’s highest court. This case has been cited as precedent over 800 times in subsequent court decisions.

Perri v. Gibert, 14 AD2d 681
This case established key principles on application of common law indemnity. It has been subsequently cited as precedent 300 times.

Bill obtained dismissal of a Taiwanese bicycle manufacturer on jurisdictional grounds. The plaintiff alleged wrongful death action.

Higgins v. West 50th, 94 AD2d 522

Symonds v 1114 Avenues of America, 7 Misc.3d 1008
Bill forestalled a finding of absolute liability under New York Labor Law. He accomplished this by using an OSHA expert and toxicologist to establish proof of alcohol use and impaired balance by the plaintiff.
