Misuse of authority in general means wrong and improper exercise of authority for the purpose not intended by law. In order to prove the charge or allegation of misuse of authority, at least two basic ingredients that is mens rea and actus rea of crime have to be necessarily established and in case any one them is found missing, offense is not made out.
Mens rea in context to misuse of authority means to act in disregard of law with conscious knowledge that act was being done without authority of law and except in case of strict liability, element of mens rea is necessary constituent of crime.
Offense of corruption and corrupt practices within the meaning to section 9 (a) (vi) of national accountability ordinance 1999, is not an offense of strict liability, therefore use of authority without object of illegal gain or pecuniary benefit or undue favor to any other person with some ulterior motive, may not be a deliberate act to constitute an offense.
Mens rea for an offense under national accountability ordinance 1999, is found in two elements i.e. conscious misuse of authority and illegal gain or undue benefit. In absence of anyone of such basic components of crime, misuse of authority is not culpable.
Prosecution must establish mens rea and actus rea of crime to establish charge. Without proof of such elements of crime, mere misuse of authority has no penal consequence.
