Acting in Authority
Sections 25 to 31 concern the "Protection of Persons Administering and Enforcing the Law".
Protection of persons acting under authority
25. (1) Every one who is required or authorized by law to do anything in the administration or enforcement of the law
- (a) as a private person,
- (b) as a peace officer or public officer,
- (c) in aid of a peace officer or public officer, or
- (d) by virtue of his office,
is, if he acts on reasonable grounds, justified in doing what he is required or authorized to do and in using as much force as is necessary for that purpose.
(2) Where a person is required or authorized by law to execute a process or to carry out a sentence, that person or any person who assists him is, if that person acts in good faith, justified in executing the process or in carrying out the sentence notwithstanding that the process or sentence is defective or that it was issued or imposed without jurisdiction or in excess of jurisdiction.
When not protected
(3) Subject to subsections (4) and (5), a person is not justified for the purposes of subsection (1) in using force that is intended or is likely to cause death or grievous bodily harm unless the person believes on reasonable grounds that it is necessary for the self-preservation of the person or the preservation of any one under that person’s protection from death or grievous bodily harm.
(4) A peace officer, and every person lawfully assisting the peace officer, is justified in using force that is intended or is likely to cause death or grievous bodily harm to a person to be arrested, if
- (a) the peace officer is proceeding lawfully to arrest, with or without warrant, the person to be arrested;
- (b) the offence for which the person is to be arrested is one for which that person may be arrested without warrant;
- (c) the person to be arrested takes flight to avoid arrest;
- (d) the peace officer or other person using the force believes on reasonable grounds that the force is necessary for the purpose of protecting the peace officer, the person lawfully assisting the peace officer or any other person from imminent or future death or grievous bodily harm; and
- (e) the flight cannot be prevented by reasonable means in a less violent manner.
Power in case of escape from penitentiary
(5) A peace officer is justified in using force that is intended or is likely to cause death or grievous bodily harm against an inmate who is escaping from a penitentiary within the meaning of subsection 2(1) of the Corrections and Conditional Release Act, if
- (a) the peace officer believes on reasonable grounds that any of the inmates of the penitentiary poses a threat of death or grievous bodily harm to the peace officer or any other person; and
- (b) the escape cannot be prevented by reasonable means in a less violent manner.
R.S., 1985, c. C-46, s. 25; 1994, c. 12, s. 1.
26 Every one who is authorized by law to use force is criminally responsible for any excess thereof according to the nature and quality of the act that constitutes the excess.
R.S., c. C-34, s. 26.
Use of force to prevent commission of offence
27 Every one is justified in using as much force as is reasonably necessary
- (a) to prevent the commission of an offence
- (i) for which, if it were committed, the person who committed it might be arrested without warrant, and
- (ii) that would be likely to cause immediate and serious injury to the person or property of anyone; or
- (b) to prevent anything being done that, on reasonable grounds, he believes would, if it were done, be an offence mentioned in paragraph (a).
R.S., c. C-34, s. 27.
Use of force on board an aircraft
27.1 (1) Every person on an aircraft in flight is justified in using as much force as is reasonably necessary to prevent the commission of an offence against this Act or another Act of Parliament that the person believes on reasonable grounds, if it were committed, would be likely to cause immediate and serious injury to the aircraft or to any person or property therein.
Application of this section
(2) This section applies in respect of any aircraft in flight in Canadian airspace and in respect of any aircraft registered in Canada in accordance with the regulations made under the Aeronautics Act in flight outside Canadian airspace.
2004, c. 12, s. 2.
Preventing breach of peace
30 Every one who witnesses a breach of the peace is justified in interfering to prevent the continuance or renewal thereof and may detain any person who commits or is about to join in or to renew the breach of the peace, for the purpose of giving him into the custody of a peace officer, if he uses no more force than is reasonably necessary to prevent the continuance or renewal of the breach of the peace or than is reasonably proportioned to the danger to be apprehended from the continuance or renewal of the breach of the peace.
R.S., c. C-34, s.
Arrest for breach of peace
31 (1) Every peace officer who witnesses a breach of the peace and every one who lawfully assists the peace officer is justified in arresting any person whom he finds committing the breach of the peace or who, on reasonable grounds, he believes is about to join in or renew the breach of the peace.
Giving person in charge
(2) Every peace officer is justified in receiving into custody any person who is given into his charge as having been a party to a breach of the peace by one who has, or who on reasonable grounds the peace officer believes has, witnessed the breach of the peace. R.S., c. C-34, s. 31.
When considering the use of potential excessive force, the court should consider "the reasonable belief of the officer in all the circumstances as they existed at the time which belief must be justified by the facts at the time." The belief must be subjectively held as well as objectively reasonable.
