First of all would be a petitions committee, I think, to consider a number of routes in which a petition could be considered.
Secondly, you mentioned that you have an existing paper petition system. I would think about how you integrate it together with the e-petition system.
What we've ended up with here in the U.K. is in effect three petition systems: an e-petition system for the House of Commons, a written system for the House of Commons, and a written system for the House of Lords. They're all slightly different. Actually, in an integrated system, e-petitions are simply a technological way of delivering petitions quickly. So integrating them, thinking about how the e-route and the written route are similar, and what procedures and processes you want for them both, would be useful.
Then I would think very strongly about the member role you want in this process. That is absolutely vital. In the U.K. system, what we've ended up with is quite a thin form of engagement, where members of the public engage with a website. They don't really have that much engagement with Parliament and with MPs.
