Apart from occasional acts involving direct violations of the Corrupt Practices Act by the candidate himself, the statute has holes through which others can pass so readily that an election agent has been known to speak of the return of expenses as largely a farce. In fact the elaborate provisions of the law can easily be evaded if the candidate and his agent have a mind to do so. If they only keep their eyes shut tight enough, and are sufficiently ignorant of what goes on, it is very difficult to connect them with corrupt or illegal practices in such a way as to avoid the election.[232:1] An agent from another constituency may pay the railway fares of out-voters. The Primrose League, or some other body, may give picnics, teas and what not, which would be corrupt treating if done by the candidate, but for which he is not held responsible. The brewers may furnish free beer in public houses where voters are collected before going to the polls, and yet the candidate has done nothing to forfeit his seat. Nor is this an imaginary danger; for, with the introduction of what is known as the tied-house system, the publicans have come under the control of the great brewing establishments, which have to-day a huge stake in the results of parliamentary elections. Agency, in short, is a very difficult thing to establish in such cases. As Rogers, who devotes a whole chapter to the subject, remarks: "It is to conceal agency, and so to relieve the candidate from the consequences of corruption practised on his behalf, that efforts of unscrupulous men engaged in the conduct of an election have been generally directed, and it is not too much to say that an election inquiry has been more frequently baffled from a failure in the proof of agency than from all other causes put together."[232:2] [Sidenote: Or Know When Election Period Begins.]
