Effective and fair?

Sir, – Tom Parlon argues for the inclusion of "an effective and fair price variation clause" in public sector construction contracts that would apply retrospectively (Business, May 23rd).

If, before inflation was on the radar, the cost of the National Children’s Hospital under construction was already able to rise from €400 million to €1.7 billion (and which may increase further still), I would hate to see what Mr Parlon considers to be an “effective and fair price variation”. – Yours, etc,
