The appellant, an experienced recreational diver, was convicted in the Durban magistrate’s court of contravening regulation 52(a) of the Regulations made under the Marine Living Resources Act 18 of 1998. After diving off Salt Rock Beach, he was found in possession of seven east coast rock lobsters, four of which were later measured and found to be undersized (carapace less than 65 mm). The appellant claimed that he intended to measure the lobsters at his vehicle and return any undersized ones to the sea. An inspector from the KZN Nature Conservation Service disputed this, alleging that the appellant intended to leave with the catch. The magistrate rejected the appellant’s version and convicted him; the conviction was upheld by the court a quo but leave to appeal was granted to the Supreme Court of Appeal.
