2. Turning to Day's G.L.c. 93A claim, Hyman argues that even if he breached the contract, such breach of a legal obligation under commercial law cannot, standing alone, amount to an actionable unfair and deceptive act See, e.g., Framingham Auto Sales, Inc., supra, at 418; Cetkovic v. Boch, Inc., 2003 Mass. App. Div. 1, 3. However, conduct in known disregard of contractual arrangements and intended to secure benefits for the breaching party may constitute a violation of G.L.c. 93A See Clamp-All Corp. v. Foresta, 53 Mass. App. Ct. 795, 812 (2002), citing Wang Labs., Inc. v. Business Incentives, Inc., 398 Mass. 854, 857 (1986).
