Research involving adults lacking the capacity to consent: The Mental Capacity Act 2005 (slides)


Summery:
Since October 2007, England and Wales have carefully regulated research upon adults who lack the ability to consent. However, in Scotland and Northern Ireland, there are different regulations for this issue.   The speaker talks about the range and different parts of the MCA (Mental Capacity Act), and who would qualify to need this act to protect them. He also talks about what the MCA requires and all the proceses that each person must go through in order to do research upon a person who lack the ability to consent.

Questions:

1. Should there be a state law that governs research and development?

2. Should the law, given that there is one, be complicated and require a long process and have detailed specifics on who falls under the need for protection from the Mental Capacity Act?
