14 Years

That's the maximum prison time for someone convicted of attempting to bribe a member of parliament. Here's the relevant section of the criminal code (emphasis mine):

Bribery of judicial officers, etc.

119. (1) Every one is guilty of an indictable offence and liable to imprisonment for a term not exceeding fourteen years who

(a) being the holder of a judicial office, or being a 119. (1) (a) ">member of Parliament or of the legislature of a province, directly or indirectly, corruptly accepts, obtains, agrees to accept or attempts to obtain, for themselves or another person, any money, valuable consideration, office, place or employment in respect of anything done or omitted or to be done or omitted by them in their official capacity, or

(b) directly or indirectly, corruptly gives or offers to a person mentioned in paragraph (a), or to anyone for the benefit of that person, any money, valuable consideration, office, place or employment in respect of anything done or omitted or to be done or omitted by that person in their official capacity.

Whoever made this offer to Mr. Cadman, and there is all evidence that an offer was in fact made, should be looking for a criminal lawyer right about now. Now, who would have the authority to "legitimately represent the party"? Mr. Harper knows, or at least he used to know.
