Transparency of Lobbying, Non-Party Campaigning and Trade Union Administration Bill

It seems to me that the kernel of the problem is that this is a Bill to regulate lobbying. An important part of an MP’s job is to lobby for his or her constituency and constituents, and we are paid salaries, so in that sense we are paid lobbyists; but surely that part of our role, like every other part of the role, must be immune from the interventions of the court and must not be in any way modified by the legislation before us.
