The expenses of the Health Service Commissioner for Wales shall, so far as they cannot be met out of income received by him, be met by the Assembly.

Those expenses include any sums payable by the Health Service Commissioner for Wales in consequence of a breach, in the course of the performance of any of his functions, of any contractual or other duty (whether that breach occurs by reason of his act or omission or that of a member of his staff or any other person assisting him in the exercise of his functions).
