In certain countries, in which the voice of the people has a more especial control over the hand of the legislator, nothing can exceed the dread which they are under of seeing any effectual provision made against the offenses which come under the head of defamation, particularly that branch of it which may be styled the political. This dread seems to depend partly upon the apprehension they may think it prudent to entertain of a defect in point of ability or integrity on the part of the legislator, partly upon a similar apprehension of a defect in point of integrity on the part of the judge.
