Protests

11. The Draft Bill provides an opportunity to re-balance the right to protest outside Parliament against the right of Parliament to operate effectively and without hindrance. How should this balance be struck?

12. Should Parliament be treated any differently from any other part
of the country in terms of managing protests? How should the legitimate expectations of Parliamentarians and Parliamentary authorities be defined?

In particular, would the repeal of sections 132 to 138 of Serious Organised Crime and Police Act give rise to a need for new powers for the police or other authorities to:
(i) Ensure free access to, from and around the Parliamentary Estate and to enable Parliamentarians to discharge their roles and responsibilities,
(ii) Restrict the use of loudspeakers,
(iii) Take account of the particular security risk,
(iv) Protect Parliament Square as a world heritage site,
(v) Prevent permanent demonstrations in Parliament Square,
(vi) Ensure equal access to the right to protest.

13. Are Sessional Orders (Orders passed by Parliament which impose an obligation on the Metropolitan Police Commissioner) still an appropriate means to manage protests around Parliament?
