Parks Regulation Act 1872

Its "First Schedule" listed offences within the Royal Parks for which people could be arrested by the park keepers and fined a maximum of £5 (Section 4), with the offence of giving a false address to the keeper set at the same rate by Section 5 and that of assaulting a park keeper at £20 or a maximum of six (England) or three (Scotland) months' imprisonment with or without hard labour by Sections 6 and 15.[2] Any new rule under that Schedule had to be placed before both Houses of Parliament and removed if they disapproved it within a month (Section 9).[2] Regulations "to be observed in pursuance of this Act" were to be publicly displayed in the Parks (Section 10).[2] The Act was not to affect, prejudice or derogate rights of way (Section 11), any previous Acts (Section 12), any Crown rights (Section 13) or the Metropolitan Streets Act 1867 (Section 14).[2]

Drawing on the common law concept of the hue and cry, Section 5 granted a park keeper and "any persons whom he may call to his assistance" the right to arrest people for the offences in Schedule 1 and Sections 5, 6 and 15.[2] Section 7 gave park keepers all the "powers, privileges, ... immunities... duties and responsibilities" as police constables in the district in which their Park fell (mostly the Metropolitan Police District), and Section 8 granted all the same "powers, privileges, and immunities" to police constables of the relevant district within the bounds of the Parks.[2]
