Under the Control of Narcotic Substances (CNS) Act, 1997 (commonly referred to in ANF exam preparation), the rule of plea of alibi applies to:

A plea of alibi is a legal defence available to the accused person. By raising this plea, the accused asserts that they were at a different location at the time the offence was committed, making it impossible for them to have committed the crime. Under Pakistani evidence law and in prosecutions under the Control of Narcotic Substances Act, 1997, an accused who relies on an alibi is expected to produce evidence supporting that claim. Thus, the plea of alibi is specifically related to the accused.
