Part 3: Public order Section 76: Obstruction of vehicular access to Parliament
This section makes it an offence for an individual to fail to comply with the direction of a police officer to stop, or not start, obstructing the passage of a vehicle into or out of the Parliamentary Estate. It does so by amending Part 3 of the Police Reform and Social Responsibility Act 2011 (the "PRSRA").
	Part 3 (comprising sections 141 to 149) of the PRSRA provides powers in relation to prohibited activity in the controlled areas of Parliament Square and of the Palace of Westminster, defined in sections 142 and 142A respectively (see also the map annexed to the guidance available here ).
	Section 143 of the PRSRA provides that a constable or other authorised person who has reasonable grounds for believing that a person is doing, or is about to do, a prohibited activity, may direct the person to cease doing that activity or not to start doing it. Failure to comply with the direction without reasonable excuse is a criminal offence and is punishable on summary conviction by an unlimited fine.
	Subsection (2) extends the Palace of Westminster controlled area as defined in section 142A of the PRSRA. The controlled area is extended to include Canon Row, Parliament Street, Derby Gate, Parliament Square and part of Victoria Embankment.
	Subsection (3) adds obstructing of the passage of a vehicle into or out of the Parliamentary Estate as a prohibited activity in the Palace of Westminster controlled area.
	Subsections (4) and (5) provide that the extension of the Palace of Westminster controlled area does not affect directions, orders, or authorisations made or given in relation to that area before this Section comes into force, which will continue to apply in relation to the Palace of Westminster controlled area as originally defined.
