The penultimate paragraph of Stuart Pemble’s article ā€œHave I really been negligent?ā€ (8 October, page 73) leads me to the view that he is wrong and Rudi Klein is, as usual, right

He comforts us that ā€œthe client’s collateral warranties will ensure recourse against the architect and engineer for any defects and inadequacies in their designā€. ā€œEnsure recourseā€ seems to imply that the client is on to a sure winner when something goes wrong. Unfortunately, the onus has always been on the client to prove negligence and … oh, has anyone ever offered an article on the history of collateral warranties in the English courts?
