42 The plaintiff relied on the judgment of Brennan J in Mengel at 355 where, after pointing out that the tort was well established, he commented that less clearly established were the principles which define the liability imposed on a public officer who, by use of his position or power, causes loss to another. Brennan J continued (citations omitted):
"The starting point is to identify the class of public officers. Best CJ identified the class in these terms in Henly v Mayor of Lyme:
'Now I take it to be perfectly clear, that if a public officer abuses his office, either by an act of omission or commission, and the consequence of that, is an injury to an individual, an action may be maintained against such public officer. The instances of this are so numerous, that it would be a waste of time to refer to them.Then, what constitutes a public officer? In my opinion, every one who is appointed to discharge a public duty, and receives a compensation in whatever shape, whether from the crown or otherwise, is constituted a public officer.
…
It seems to me that all these cases establish the principle, that if a man takes a reward, - whatever be the nature of that reward, whether it be in money from the crown, whether it be in land from the crown, whether it be in lands or money from any individual, - for the discharge of a public duty, that instant he becomes a public officer; and if by any act of negligence or any act of abuse in his office, any individual sustains an injury, that individual is entitled to redress in a civil action.'
The tort is not limited to an abuse of office by exercise of a statutory power. Henly v The Mayor of Lyme was not a case arising from an impugned exercise of a statutory power. It arose from an alleged failure to maintain a sea wall or bank, the maintenance of which was a condition of the grant to the corporation of Lyme of the sea wall or bank and the appurtenant right to tolls. Any act or omission done or made by a public official in purported performance of the functions of the office can found an action for misfeasance in public office'."
