Abstract
The Mental Capacity Act 2005 placed for the first time research concerning adults lacking mental capacity upon a statutory footing. However, while the legislation which regulates the inclusion of such adults in ‘intrusive research’ safeguards researchers and research participants alike some controversy remains as to its implementation. This paper focuses upon two specific issues raised by the legislation. First, what constitutes ‘intrusive’ research and whether all issues concerning research involving adults lacking mental capacity should be referred to NHS research ethics committees. Secondly, the role of one of the statutory safeguards–the ‘consultee’. These are individuals who are to be consulted regarding the inclusion of adults lacking mental capacity in research. It contrasts the ‘personal’ and ‘nominated’ consultees and considers whether there is a risk that the legislation may result in a new ‘quasi profession’ of consultees in the future.
