Among his many publications, the most notable were his seminal textbooks
Kontraktereg en Handelsreg (1949, with J.P. Yeats) and
Strafreg (1948, with H.L. Swanepoel), which saw several re-editions until the 1980s. With these works, de Wet abandoned the prevailing tradition of constructing legal rules from
case law. Inspired by European
civil law, he sought instead to construct a consistent framework of terms and principles to serve as a benchmark for case law itself. Through his work, de Wet enhanced the status of his native
Afrikaans by making it a language of scientific legal discourse. His influence particularly on the law of
contracts and on
penal law was immense. De Wet was known for his acerbic and often amusing criticism of judgments and has been described by
Edwin Cameron as the "enfant terrible of the judiciary". This undeferential style, together with his intellectual approach, characterised by
critical rationalism and self-assurance, had a liberating impact in the intellectual climate of
apartheid-era South Africa. De Wet was awarded honorary doctorates by the University of Cape Town and the
Rand Afrikaans University (now the
University of Johannesburg). ==References==
