Re-opening of some businesses, 15 August 2020 The regulations were amended on 15 August 2020, after a further 21 days, by The Health Protection (Coronavirus, Restrictions) (No. 2) (England) (Amendment) (No. 3) Regulations 2020 (SI 2020/863). Legal basis As with the original regulations, SI 2020/863 was introduced by Secretary of State for Health and Social Care, Matt Hancock, using emergency powers under the Public Health (Control of Disease) Act 1984. The legal basis for the use of the powers was stated to be as before. The regulations were laid before parliament on 14 August 2020, and came into force on 15 August. The Secretary of State again used section 45R of the 1984 act to enact the regulations "by reason of urgency" subject to retrospective approval by resolution of each House of Parliament within twenty-eight days. Changes to the regulations The amendments allowed certain further businesses to re-open, specifically indoor casinos, indoor skating rinks, indoor play areas, bowling alleys and conference centres and exhibition halls.

Anyone who, without reasonable excuse, hosted or facilitated a gathering of more than thirty people that: constitutes an indoor rave (as defined by s63 of the Criminal Justice and Public Order Act 1994), takes place in a private dwelling (or in an adjacent garden or yard), or takes place in a public outdoor space (other than land used as a visitor attraction, or which is part of business or charitable premises) was liable to a fixed penalty of £10,000. Once a penalty notice had been issued, there was no discretion as to the amount, which the regulations specify "must be £10,000". The penalty did not apply to anyone hosting a larger gathering that was specifically permitted, including those that were: reasonably necessary for work, voluntary or charitable purposes; or education or training
