William Flack has made another considered post on the issue of mental capacity for the purposes of Civil Procedure Rule 21 on his blog. He has also begun a wiki on the topic, which could be a very useful step. (For those not sure what a wiki is, see here, in self referential kind of way).
Contributions are apparently invited, but, despite me having enthusiatically created a user account, there doesn’t seem to be a way to add to or edit the pages at the moment – looks like an issue with permissions, I hope.
Edit 6/05/08 – One has to be added to those permitted to edit – and then it works. Anyone interested should contact William Flack to get permission, which can be done via the Wiki page, I think. Think up a decent username first!
