HONG KONG: Hong Kong leader Carrie Lam on Friday (Oct 4) invoked a rarely used colonial-era law to ban protesters from wearing face masks.
What does the new law say and why does it matter?
During the four months of protests, face masks have become ubiquitous as demonstrators try to avoid being identified by police. Respirators have also been used to deal with tear gas.
The new law makes it illegal to wear a mask at a sanctioned or unsanctioned rally, with up to a year in prison for transgressors.
Hong Kongers will still be allowed to wear face masks in the street – a common practice in a city ever since a SARS outbreak killed more than 300 people in 2003.
But police are allowed to force people to take their masks off, with six months in jail for those who refuse.
Exemptions have been made for legitimate religious and medical reasons and for those who need to wear masks for their jobs – such as journalists donning gas masks during tear gas clashes.
WHY IS IT SIGNIFICANT?
This is a watershed moment for Hong Kong. It is the first time in 52 years that these emergency powers have been invoked and the only time since the city was returned to China by Britain in 1997.
For the last few decades all of Hong Kong's laws have passed through the city's parliament, where they are discussed, debated and scrutinised.
But the Emergency Regulations Ordinance allows the chief executive to bypass that legislature altogether.
Critics see this as a slippery slope and a move that undermines the city's reputation for being a commercial and legal hub built on rule of law and a trustworthy judiciary.
WHAT ARE THE PENALTIES?
Offenders will be subject to a fine of up to HK$25,000 (US$3,200) and can be jailed for up to a year, according to a statement from the Hong Kong government on Friday.
However, the prohibition excludes those with a "reasonable excuse for using a facial covering", including but not limited to pre-existing medical or health reasons, religious reasons, or if a person uses the face covering for safety while undertaking activities related to profession or employment.
If a person wearing a mask is asked to remove it by a police officer who "reasonably believes" the mask is "likely to prevent identification", and he or she does not obey, the maximum penalty is a fine of up to HK$10,000 and jail time of up to six months.
WHERE DID THIS LAW COME FROM?
It was first introduced by the British in 1922 to combat wildcat strikes by Chinese seaman who were protesting dismal wages.
Passed in a single day, it received little scrutiny and remained on the statute books.
The broad wording enables Hong Kong's leader to make "any regulations whatsoever" in the event of an emergency or imminent public danger.
The range of other powers available is extensive. It includes censorship of the media, control of ports, the appropriation of property as well as extra arrest, detention and deportation powers for the police.
The chief executive can also authorise searches without court warrants and the censorship and suppression of communications.
