Under N.J.R.E. 406, evidence of a specific, repeated, and regular business habit or practice, whether corroborated or not, would have been admissible to establish a rebuttable presumption that Altice had acted in conformity with that habit or practice. But here, Altice produced insufficient evidence of such habit or practice. And because there is no proof that Altice emailed plaintiff the critical customer service agreement, the Court does not reach whether there exists mutual assent to waive a jury trial and arbitrate the dispute.
