The plaintiff sued the police and Crown Attorneys for negligent investigation, unlawful arrest, and intentional infliction of mental suffering following an acquittal on a murder charge that involved a 'Mr. Big' operation.
The Crown Attorneys moved to strike the plaintiff's claim and a crossclaim brought by the police for negligent legal advice.
The court struck the plaintiff's claim against the Crown Attorneys, finding it barred by absolute common law immunity, which only allows claims for malicious prosecution.
However, the court refused to strike the police crossclaim for negligent legal advice, finding it was not plain and obvious that Crown Attorneys do not owe a duty of care to police when providing legal advice during an investigation.
The court also held that statutory immunity under s. 8 of the Ministry of the Attorney General Act applied to the plaintiff's claim but not the crossclaim.
