Alice's question was "What evidence is there that the initial investigation was not fit for purpose".
Answering that would require establishing criteria and then assessing the extent to which they were met. IMO.
Well the Thread Title asks the question.
I share your opinion.
Fit for purpose is a bit of a new kid on the block in the buzzword world. It was seemingly introduced by Dr John Reid when he was Home Secretary. Because Dr Reid used “not fit for purpose” as a sound bite when describing the Immigration and Nationality Directorate system as such, much improper use of the term ensued.
Dr John Reid? Do you remember him? Yes that is he the very same Dr John Reid who when Minister for Defence said we would be in and out Afghanistan without firing a shot. The phrase “Fit for purpose” however is a lot older than that, pre 1968 at least, being associated with consumer protection law and construction contract law eg FIDIC, IChemE and JCT model forms.
It is widely understood that the effect of a fitness for purpose obligation is to impose a duty of result. A party wishing to rely upon a particular obligation, however, must also demonstrate that the obligation exists.
So what is “fitness for purpose” wrt an investigation? Who has an obligation to whom, what is that obligation, what is the expected result and what penalty is there for failure to achieve the result?
It is hard to see any contract existed between parties in this instance so:
In English law the common law imposes on a professional person a standard of reasonable skill and care but specifically he/she is not required to guarantee results. Ref: The Bolam Test.
With The Bolam Test in mind, one would need to demonstrate that another investigative team working in a similar field would have found the actions of the original team unacceptable in order to sustain an unfit for purpose claim. The only proper measure we have of that is from the AC of The Metropolitan Police Service, Mr Rowley, who indicated he was content to rely on the original investigation.
