What is a petty offence?

Introduction
A petty crime/offence (Afrikaans: “‘n geringe/nietige/klein misdaad/misdryf”) means that the crime/offence concerned (usually theft-related, but see S v Visagie infra) is embodied in the Latin maxim de minimis non curat lex which literally means that “the law does not concern itself with trifles or paltriness”. Translated into Afrikaans, it means that “die reg bemoei dit nie met beuselagtighede of onbenullighede nie”.
