A state appeals court has issued a rare ruling striking an entire appellate brief after counsel allegedly “permeated” the brief with information from outside the record in an insurance coverage dispute.

In a short, one-page decision in Bialik v. AXA Equitable Life Insurance, 156898/13, the Appellate Division, First Department, denied respondent AXA Equitable Life Insurance Co.’s motion to enlarge the appellate record by submitting the plaintiff’s deposition transcript.
