Order the list by defense deadline. asc returns the soonest-expiring disputes first, desc the furthest out; disputes with no deadline are returned last either way.
Exactly one sort[field] parameter may be given per request: a second one, a repeated one, a bare sort=field, or a direction other than asc or desc all return 400.
The last link resolves in either direction, and the page it returns is the one holding the disputes with no deadline.
