The case concerned the allocation of commercial pelagic fishing rights (pilchard and anchovy) for the 2002–2005 fishing seasons under the Marine Living Resources Act 18 of 1998. The Minister (or his delegate) determined the total allowable catch (TAC) and allocated quotas using a new Operational Management Plan (OMP-02), which replaced separate pilchard and anchovy quotas with a single combined quota allocated through a mathematical formula. Foodcorp, a company with significant canning capacity, experienced a drastic reduction in its quota, while two companies without canning facilities received massive and disproportionate increases. These results were produced by the mechanical application of the formula, without any further consideration or adjustment by the decision-maker. Foodcorp challenged the allocations on review under PAJA, alleging that the formula produced irrational and unreasonable outcomes and that the decision-makers fettered their discretion.
