2. What would be the consequences if I refuse their entry?
If you are simply asked by police officers for consent to allow them entry into your premises, you may choose to refuse. However, if the police officers produce a search warrant issued by a Magistrate, or demands that you open the door on the ground that they reasonably believe a person to be arrested is inside your premises, then you must cooperate. Otherwise, you may be guilty of the offence of resisting or obstructing the police officers in the due execution of their duties and they may also break open the door for their entry.
