Supreme Court allows appeal from High Court, and sets aside declaration that legislation was unconstitutional where it conferred power on a Minister to grant licences for livestock marts and to attach conditions to such licences, on the grounds that: (a) the legislation was entitled to the presumption of constitutionality; (b) although the Minister’s powers were discretionary, he was obliged to exercise them only within the boundaries of the stated objects of the legislation; and (c) where legislation was capable of being interpreted in an unconstitutional manner, it should be presumed that the Oireachtas intended it to be interpreted in a manner that was consistent with the constitution.
