Colour of office and six-month limitation under the Bombay Police Act barred prosecution for police misconduct during investigation.

Acts by police officers done under the cloak of investigation, even if wrongful and in excess of duty, fall within section 161(1) of the Bombay Police Act when they are connected with official functions. Where wrongful confinement and assault were used to obtain information and confessions during a murder investigation, the six-month limitation applied to prosecution. Because the complaint was instituted after that period, the prosecution was time-barred and the convictions and sentences could not stand.

Issues: Whether the alleged wrongful confinement and assault by police officials, committed while investigating a suspected murder, were acts done under colour of office or in excess of duty so as to attract the six-month bar under section 161(1) of the Bombay Police Act.

Analysis: Section 161(1) bars prosecutions instituted more than six months after the act complained of where the offence or wrong was done under colour of office or in excess of duty or authority. The expression is wider than the language of section 197 of the Code of Criminal Procedure and covers acts done under the cloak of official duty, even if those acts are wrongful and in dereliction of duty. The accused were entrusted with an investigation into a suspected murder, and the confinement and assault of persons questioned in that investigation were found to be connected with that official function and to have been used as a means of obtaining information and confessions. The prosecution was instituted after the expiry of six months.

Conclusion: The impugned acts fell within section 161(1) of the Bombay Police Act and the prosecution was barred by limitation; the convictions and sentences could not stand.

Final Conclusion: The appeal succeeded and the criminal prosecution against the appellants was quashed as time-barred under the special protection afforded by the Bombay Police Act.

Ratio Decidendi: For purposes of section 161(1) of the Bombay Police Act, an act by a police officer done under the cloak of investigation, or in excess of the authority entrusted to him, is treated as an act done under colour of office and attracts the six-month bar to prosecution.
