This is the thing about consultants (and I work as one) - Our responsibility to the client extends as far as giving a full and honest appraisal of the situation and a suite of recommendations to follow. The method of analysis and appraisal needs to be done at "industry standard practice" as a minimum.

The client at the end of the day has to make the decision and if they choose not to follow our advice, the outcomes and decisions are documented.

So many times have I had clients that think they know better than the consultant, expect changes to be made because they believe they can achieve things properly by taking shortcuts.

The only way TIS would have a leg to stand on is if BSI pushed them down a path they knew wasn't the industry standard, without informing them of the normal practice. If BSI continued to push for CE mark the way TIS wanted to, whilst repeatedly saying, "we have concerns this won't be successful," then TIS have nobody to blame but themselves.
