The observations of the Privy Council in King v Henderson (1864) 10 LT (NS) 414 at 415 and those of Isaacs J in Dowling (1915) 20 CLR at 521 - 522, to which we referred earlier, represent an attempt to achieve a formulation which keeps the concept of abuse of process within reasonable bounds. To say that a purpose of a litigant in bringing proceedings which is not within the scope of the proceedings constitutes, without more, an abuse of process might unduly expand the concept. The purpose of a litigant may be to bring the proceedings to a successful conclusion so as to take advantage of an entitlement or benefit which the law gives the litigant in that event.
Thus, to take an example mentioned in argument, an alderman prosecutes another alderman who is a political opponent for failure to disclose a relevant pecuniary interest when voting to approve a contract, intending to secure the opponent's conviction so that he or she will then be disqualified from office as an alderman by reason of that conviction, pursuant to local government legislation regulating the holding of such offices. The ultimate purpose of bringing about disqualification is not within the scope of the criminal process instituted by the prosecutor. But the immediate purpose of the prosecutor is within that scope. And the existence of the ultimate purpose cannot constitute an abuse of process when that purpose is to bring about a result for which the law provides in the event that the proceedings terminate in the prosecutor's favour.
It is otherwise when the purpose of bringing the proceedings is not to prosecute them to a conclusion but to use them as a means of obtaining some advantage for which they are not designed or some collateral advantage beyond what the law offers. So, in Dowling, Isaacs J pointed out that 'if, for instance, it had been shown that the Society had simply threatened Dowling that unless he did what they had no right to demand from him, namely, give up certain names, they would proceed to sequestration, and they had proceeded accordingly, there would have been in law an abuse of the process'. However, because the Society wished to use the process for the very purpose for which it was designed, there was no abuse of process (526 - 527).
