He has written about temporal issues as they arise in the law of restitution, torts, defences, remedies and legal theory. Sam has also published on the subject of interference with privacy, and on landlord–tenant contract and agency issues. His articles appear (or are forthcoming) in the Law Quarterly Review, the Yale Law Journal, the Osgoode Hall Law Journal, and the New Zealand Law Review (among others).
