Rule Against Collateral Attacks on Court Orders
All orders made by courts with lawful jurisdiction must be obeyed unless they are set aside by proper application. Challenge to that order outside of a hearing to set aside the order is known as a "collateral attack" upon the order. It generally prohibited. The purpose of the rule is to "ensur[e] court orders are considered final and conclusive" and must be obeyed unless set aside by "an established judicial procedure".
The rule does not apply to the findings of fact underlying the order.
The rule against collateral attack has been recognized as arising from the doctrine of abuse of process whereby violations of the rule are a form of abuse.
Even where an order allegedly violates a constitutional right, the rule against collateral attack can still apply.
The rule applies to many types of orders including:
- peace bonds
- provincial administrative orders
- probation orders
- search warrants
It however has been found not to apply in circumstances such as:
- a pre-trial severance order
- Probation Orders
An established procedure to attack a probation order would include making application under s. 732.2(3) to amend the order.

R v Wilson, 1983 CanLII 35 (SCC),  2 SCR 594, per McIntyre J at 599 ("It has long been a fundamental rule that a court order, made by a court having jurisdiction to make it, stands and is binding and conclusive unless it is set aside on appeal or lawfully quashed. It is also well settled in the authorities that such an order may not be attacked collaterally—and a collateral attack may be described as an attack made in proceedings other than those whose specific object is the reversal, variation, or nullification of the order or judgment.")

Garland v Consumers’ Gas Co., 2004 SCC 25 (CanLII),  1 SCR 629, per Iacobucci J, at para 71 ("The doctrine of collateral attack prevents a party from undermining previous orders issued by a court or administrative tribunal. Generally, it is invoked where the party is attempting to challenge the validity of a binding order in the wrong forum, in the sense that the validity of the order comes into question in separate proceedings when that party has not used the direct attack procedures that were open to it (i.e., appeal or judicial review)")
