In the Wikipedia Article "Lobbying" there is such a sentence:
Governments often define and regulate organized group lobbying that has become influential.
What does 'define' mean in this sentence? Whether a lobbying is influential or not is about how it comes out rather than how you define it, so it doesn't need any organisation to make a definition or something, right?
I think the sentence might mean governments often make a list of influential lobbyings and regulate them but I'm not sure.
