Canadian Criminal Law/Offences/Obstruction of a Peace Officer

Legislation
The Criminal Codes states:

Proof of Offence
In addition to the essential elements of identity, time and jurisdiction, the prosecution shall prove that:
 * 1) the complainant was a peace officer within the meaning of s. 2
 * 2) the peace officer was engaged in lawful duty at all relevant times
 * 3) If the officer was undertaking an arrest, there were reasonable grounds to do so
 * 4) the accused knew that the complainant was a peace officer (e.g. could see the officer's uniform, utterance of officer)
 * 5) the accused obstructed the officer and
 * 6) the obstruction was wilful

Interpretation
Obstruction In R v Soltys (1980) 56 CCC (2d) 43 at p 45, the BC Court of Appeal, cited Black's Law Dictionary, stated "obstruct" means "to impede; to interpose impediments to the hindrance or frustration of some act or service; such as to obstruct an officer in the execution of his duty".
