Administrative - Collateral Attack Rule'Collateral attack' is another procedure-dependent doctrine, similar to 'abuse-of-process' - indeed, it could have been located in abuse-of-process without straining legal logic. Collateral attack prohibits the use of indirect (ie. 'collateral') procedures to challenge otherwise validly arrived-at legal results. As such it is a legal defence.
It's a relatively new doctrine, and it's abstract features are not yet articulated well - as such, I won't attempt to sub-categorize the cases yet, only present them as they occur.
