"…..if a candidate or election agent fails to comply with the requirements of section 81 or section 82…he shall be guilty of an illegal practice."
"There had been some debate in the election courts at the turn of the century as to whether ignorance of the law was 'inadvertence'. McCardie J resolved it in Nichol [v Fearby[1923] 1 KB 480 ]. In that case the question was similar to the present one, in that two municipal candidates, required to send both a return of election expenses and a declaration verifying it, failed to do so within the specified period and sought relief 'by reason of inadvertence… and not by reason of any want of good faith'. The inadvertence they each put forward was ignorance of their statutory obligations, McCardie J said (at 497-498): 'In my view the word "inadvertent" may be used according to our jus et norma loquendi as indicating either a negligent act, as distinguished from a careful act, or as indicating an unintentional, as distinguished from an intentional act. So, too, of an omission, as well as of an act… In my own view it is clear that ignorance of the law may fall within the word "inadvertence" … In Ex parte Walker (1889) 22 Q.B.D. 384 the Court of Appeal held and in my view unmistakeably held, that ignorance of the law may be "inadvertence"
'The phrase is a somewhat curious one. It implies that inadvertence may be "a reasonable cause," and I assume that what is meant is that there must exist some reasonable explanation…. To say that a man has not adverted to a particular duty, and has consequently failed to perform it, may either imply gross and reprehensible negligence on his part, or again, it may mean that, being a human being, he has, thorough frailty, mad a mistake. In either case he has been guilty of negligence.'
'As regards inadvertence, of course, it is a matter of degree. It is not every act of inadvertence which amounts to negligence. Equally in certain circumstances inadvertence may well amount to neglect.'
