Probable cause / reasonable grounds

Definition

The standard of suspicion required before a warrant may issue or a warrantless search may occur. In US law, probable cause requires a reasonable belief, based on articulable facts, that evidence of a crime will be found. The equivalent in England and Wales is 'reasonable grounds to believe'; in India the BNSS uses 'reason to believe'.
