HONG KONG: Hong Kong's Court of Appeal on Wednesday banned "Glory to Hong Kong," a protest song penned during massive pro-democracy demonstrations in 2019, which was already all but illegal after Beijing imposed a national security law.

The song grew massively popular during the huge and occasionally violent protests and was also secretly recorded by an anonymous orchestra. Its defiant lyrics incorporate the key protest slogan "Liberate Hong Kong, revolution of our times."

Angering the city's government, "Glory to Hong Kong" has, in recent years, been played at several international sporting events, with event organizers mistaking it for the Chinese territory's anthem.

Hong Kong is a semi-autonomous territory with no anthem of its own and uses China's "March of the Volunteers."

Wednesday's ban comes after a campaign by the city's authorities against the song, which has seen them demand that it be removed from internet search results and content-sharing platforms.

Reversing a lower court's decision last year, appellate judge Jeremy Poon wrote in a ruling that the composer of the song had "intended it to be a 'weapon' and so it had become."

"It had been used as an impetus to propel the violent protests plaguing Hong Kong since 2019. It is powerful in arousing emotions among certain fractions of the society," Poon said, adding that the song "has the effect of justifying and even romanticizing" the protests.

"[We] are satisfied that an injunction should be granted," he added, granting an order that would stop a range of acts, including broadcasting and performing the song "with criminal intent."

The song can also no longer be disseminated or reproduced in any way on internet-based platforms, though the injunction contained exceptions for "academic activity and news activity" — a tweak the government made after earlier questioning by judges.

Civil injunction is needed as "criminal law alone would not achieve the public interest purpose of safeguarding national security," Poon said.

Wednesday's decision would make "Glory to Hong Kong" the first song to be banned in the former United Kingdom colony since it was handed over to China in July 1997.

Soon after the judgment was handed down, Beijing authorities said the ban was a "necessary measure."

"Stopping anyone from employing or disseminating the relevant song... is a legitimate and necessary measure by [Hong Kong] to fulfill its responsibility of safeguarding national security," Chinese Foreign Ministry spokesman Lin Jian told a regular briefing on Wednesday.

'Policing the internet'

The Hong Kong government's first attempt to get an official injunction was refused by the High Court last year in a surprise ruling, which said a ban could have a "chilling effect" on innocent third parties.

The injunction also did not have "any real utility," the court said then, which the appellate judges disagreed with on Wednesday.

One key issue cited during the appeal hearings was how the government's proposed order would affect internet platform operators — mirroring concerns raised internationally about the free flow of information in Hong Kong.

Officials had in the past demanded tech giants such as Google to remove "Glory to Hong Kong" from their search results and video platforms but were largely rebuffed.

Wednesday's judgment said an injunction order was "necessary" because internet platform operators like Google "indicated that they are ready to accede to the Government's request if there is a court order."

Hong Kong-based cybersecurity expert Anthony Lai explained that if a platform were to comply with the ban, they would have to make sure the song cannot have a Hong Kong internet protocol address or Hong Kong users cannot access the song.

But both ways would be as difficult as "pulling a cow to climb up a tree," he said.

"I understand the government's need to defend national security, but I worry it would take up too much of their resources to police the whole internet," Lai told AFP.

After the protests were quashed and Beijing's national security law enacted in 2020, public dissent has largely been absent, and the bulk of pro-democracy activists and opposition politicians have either been arrested, silenced or fled Hong Kong.
