Re H  EWCOP 52,  MHLO 89
"There are two provisions in the Mental Capacity Act 2005 ('MCA') that seem to contradict each other. Section 16(4)(b) envisages that a deputyship appointment will be of limited duration, whereas section 19(5) facilitates an appointment that could last for decades. ... When it comes to the crunch, section 16(4)(b) trumps section 19(5) because it is a principle to which the court must have regard when deciding whether it in P's best interests to appoint a deputy, while section 19(5) is simply a discretion conferred upon the court, once it has decided to appoint a deputy."
