The Mental capacity Act 2005 provides a statutory framework for people who lack the capacity to make decisions for themselves, or for people who want to make provision for a time when they will be unable to make their own decisions. This code of practice, which has statutory force, provides information and guidance about how the Act should work in practice. It explains the principles behind the Act, defines when someone is incapable of making their own decisions and explains what is meant by acting in someone's best interests. It describes the role of the new Court of Protection and the role of Independent Mental Capacity Advocates and sets out the role of the Public Guardian. It also covers medical treatment and the way disputes can be resolved.
