 These are cases of "voluntary cessation" on the part of the defendant; questions that involve secondary or collateral legal consequences; questions that are "capable of "repetition," yet evading review"; and questions involving class actions where the named party ceases to represent the class.Where a defendant is acting wrongfully, but ceases to engage in such conduct once a litigation has been threatened or commenced, the court will still not deem this correction to moot the case.Obviously, a party could stop acting improperly just long enough for the case to be dismissed and then resume the improper conduct.
