Decision Making Ability - Capacity
Pp. 9-12 (4)
Jeffrey C. McILwain
Capacity is also known as competence and is about decision making ability. The simplest basis of capacity is the ability to understand and retain information and then to weigh it up and then decide. It is presumed in law that all adults have such ability and it is also taken that older children (who may be referred to " young persons" ) can have the ability. However, if an adult or child / young person lack such a complete ability then strong measures must be in place to protect them.
