moderate changeintent mostly kept
The bill kept its core purpose of making it an offence to wear a mask or disguise during a riot or unlawful assembly. The only change was raising the maximum term for the indictable offence from five years to ten years.
- The maximum sentence for the indictable offence was raised.
Before: “liable to imprisonment for a term not exceeding five years.”
After: “liable to imprisonment for a term not exceeding 10 years.”
How precisely it is written
mixedChallenging the law: ModerateDisputing a charge: Moderate
The bill adds clear maximum penalties and cross-references to existing Criminal Code subsections on riots and unlawful assemblies. However, the new offences hinge on the undefined phrase 'without lawful excuse' and the purpose of concealment, both of which invite argument.
Open to argument
“while wearing a mask or other disguise to conceal their identity without lawful excuse”
The term 'lawful excuse' is undefined and subjective, allowing broad dispute over what counts as justification.“mask or other disguise to conceal their identity”
Whether an item qualifies as a disguise and whether the wearer intends concealment are open to factual and interpretive debate.
Clear-cut
“liable to imprisonment for a term not exceeding 10 years”
The maximum sentence is stated as a fixed number with no further discretion granted to officials.“an indictable offence and liable to imprisonment for a term not exceeding five years; or (b) an offence punishable on summary con”
The two-tier penalty structure is set out in objective, numbered alternatives.
Discretion. No power is delegated to ministers or regulations; any discretion resides only in the courts' interpretation of 'lawful excuse' when applying the Criminal Code provisions.
Challenging the law itself. The undefined 'lawful excuse' and purpose element could support a vagueness or overbreadth argument under section 7 of the Charter.
Disputing a charge under it. An accused can readily dispute whether the item was worn 'to conceal' identity or whether a lawful excuse existed, both of which turn on subjective elements.
Read by a language model from the royal assent text; every quoted phrase appears in the bill. A reading of the drafting, not legal advice.
