His notable works include 'The Laws and Customes of Scotland in Matters Criminal,' which provided a comprehensive overview of criminal law in Scotland. Through his writings, Mackenzie not only shaped legal thought but also influenced the development of legal practices in Scotland. His legacy endures as a pivotal figure in the evolution of Scottish jurisprudence, illustrating the intersection of law, politics, and society in the 17th century.
