is a common law tort
, where a plaintiff
alleges he or she was held in custody
without probable cause
or without an order issued by a court of competent jurisdiction. Although it is possible to sue law enforcement officials for false arrest, the usual defendants in such cases are private security firms.
In most jurisdictions, the arrest powers of police
and police agents are in excess of those afforded to ordinary citizens (see citizen's arrest
). However, the powers of police officers to arrest are not unlimited. Generally speaking:
- Anyone may arrest a person if he or she possesses an arrest warrant issued by an appropriate court. In the United States, this includes bounty hunters (agents of bail bondsmen) acting under the authority of a bench warrant to bring a criminal defendant who has skipped bail to court for trial.
- A police officer, or a person authorized by a jurisdiction's police powers act, may arrest anyone whom the officer has reasonable and probable cause to believe has committed any criminal offence. However, in the case of a misdemeanour, summary conviction offence, or non-criminal offence (such as a municipal by-law offence) the officer may arrest the suspect only long enough to identify the suspect and give the suspect a summons to appear in court, unless there is reason to believe he or she will not appear in answer to the summons.
- Any person may arrest someone suspected of committing a felony or indictable offence, as long as the arresting person believes the suspect is attempting to flee the scene of the felony. A person cannot be arrested on suspicion of committing a felony well after the fact unless the arresting officer possesses an arrest warrant.
Citizens and Businesses
Most cases of false arrest involve accusations of shoplifting
, and are brought against security guards
and retail stores. A guard cannot arrest someone merely on the suspicion that person is going to commit a theft. In most jurisdictions, there must be some proof that a criminal act has actually
been committed. For example, a guard does not have reasonable and probable cause if a shopper has not yet paid for merchandise they are carrying in the belief that they person intends to leave without making payment. Instead, there must be an actual act committed the person must
make an actual attempt to leave the store without paying for the merchandise.
In the United States and other jurisdictions, police officers and other government officials are shielded from false arrest lawsuits through a process known as qualified immunity
. This doctrine protects such officials from liability when engaged in discretionary actions such as arrests of suspects. However, the officer's actions must still not violate "clearly established law," or this protection is void. This includes executing an arrest warrant against the wrong person.
An example of this doctrine being tested is Sorrell v. McGuigan (4th Cir. 2002). A police officer detained the plaintiff based on the description of a suspect who had committed a robbery nearby, and proceeded to do a simple search for weapons. The witness who reported the robbery arrived at the scene and stated the plaintiff was the wrong person. However, the officer still arrested the plaintiff for possession of a concealed weapon, a 3" folding knife. In Maryland, non-automatic folding knives are not considered weapons under state law regardless of their length, and the lack of length limit had been upheld multiple times in the state supreme court. However, the officer erroneously believed the knife to be a weapon. The plaintiff was never prosecuted as there was technically no crime, and sued the police officer for false arrest. The officer's qualified immunity was denied by the court, and this decision was upheld in the US Court of Appeals.
have been subject to suits for false arrest when they attempt to execute a bench warrant
outside of the United States
. In Canada
, only police officers are permitted to execute bench warrants, even though American bench warrants issued by any court are valid in any U.S. state. In at least two prominent cases, bounty hunters were charged with kidnapping
after taking custody of a bail jumper outside of the United States and bringing them back to the court that issued the warrant.
There have been some cases where police officers or bounty hunters have executed valid arrest warrants against the wrong person. Although many false arrest suits result in only nominal damages, such mistakes usually result in large awards against the arresting officers.
