As I have said before, there is no actual legislation that prevents someone voting for their own dispensation but if you actually look at the reasons why and when a dispensation should be granted, and consider the whole concept of what declaration of interests, particularly disclosable ones, are intended to achieve, it seems incongruous that someone should be permitted to vote on a matter which would avoid the application of the rules on speaking and voting on matters in which they have an interest. Irrespective of the legislation, I would personally not support a move to allow someone applying for a dispensation to vote on their own application.
