Unless displaced by particular provisions of this title, the principles of law and equity, including the law merchant, and the law relative to capacity to contract, principal and agent, estoppel, fraud, misrepresentation, duress, coercion, mistake, bankruptcy, or other validating or invalidating causes supplement its provisions.
Notes
Establishes that general principles of law and equity supplement the title unless a specific provision displaces them, expressly including law merchant and rules on contractual capacity, agency, estoppel, fraud, misrepresentation, duress, coercion, mistake, bankruptcy, and other validating or invalidating causes. Those background principles yield when particular provisions of the title control instead.
