Charter Rights and Police Conduct: Overview

The Canadian Charter of Rights and Freedoms (1982) guarantees fundamental rights, which significantly influence police conduct. Key sections relevant to policing include:

Section 8: Right against unreasonable search and seizure

Section 9: Right against arbitrary detention or imprisonment

Section 10: Right upon arrest or detention (to be informed, to counsel)

Section 11: Rights in criminal proceedings, including fair trial and presumption of innocence

Judicial interpretation of these rights often balances public safety with individual freedoms, particularly in cases of searches, arrests, interrogations, and evidence admissibility.

Key Judicial Interpretations with Case Laws

1. R. v. Oakes (1986)

Facts: The case involved possession of drugs and challenged the reverse onus provisions under Narcotics Act. While not a police conduct case per se, it established principles for justifying Charter infringements.
Holding: Supreme Court developed the Oakes test, which requires:

The government must have a pressing and substantial objective

Measures must be proportional, minimally impairing, and rational
Significance: Police practices infringing Charter rights (e.g., searches, detention) must satisfy proportionality and necessity tests.

2. R. v. Collins (1987)

Facts: Police conducted an unlawful search of a student’s room without consent or warrant. Evidence was seized.
Holding: Supreme Court ruled that evidence obtained in violation of Section 8 may be excluded if its admission would bring administration of justice into disrepute.
Significance: Reinforced the exclusionary rule and clarified limits of police authority under unreasonable search standards.

3. R. v. Therens (1985)

Facts: Police arrested a driver and failed to inform him of the right to counsel (Section 10(b)) before obtaining a breath sample.
Holding: Supreme Court held that evidence obtained without informing the accused of their rights is inadmissible, emphasizing right to legal advice as fundamental to fair police conduct.
Significance: Directly impacted police arrest procedures, requiring them to advise detainees immediately of their rights.

4. R. v. Grant (2009)

Facts: Police conducted a street stop without reasonable suspicion, found drugs, and arrested the accused.
Holding: Supreme Court elaborated a three-part test for admitting evidence under Section 24(2) when Charter rights are violated:

Seriousness of the Charter breach

Impact on the accused’s rights

Society’s interest in adjudication on the merits
Significance: Balanced individual rights against public interest, shaping evidence admissibility in police misconduct cases.

5. R. v. Feeney (1997)

Facts: Police entered the home of a suspect without a warrant and arrested him for murder.
Holding: Supreme Court held that police must obtain a warrant to enter private dwellings except in exigent circumstances. Arrests without warrant in a private home violated Section 8.
Significance: Reinforced the sanctity of privacy in homes and clarified limits on police powers.

6. R. v. Singh (2007)

Facts: Police detained the accused at a checkpoint and conducted searches without reasonable suspicion.
Holding: Court ruled the search violated Section 8, and the resulting evidence was excluded.
Significance: Highlighted that random searches must be justified, police cannot arbitrarily interfere with individual liberties.

7. R. v. M. (M.R.) (1998) – Detention and Interrogation

Facts: Accused detained for questioning without proper advisement of rights.
Holding: Supreme Court emphasized that informing detainees of their right to counsel (Section 10(b)) is crucial for voluntariness of statements.
Significance: Reinforced safeguards against coercive police interrogation.
