In its filing, Riverway Law outlines three primary grounds for why Hamas should be removed from the terrorist list.

A growing wave of condemnation is mounting in the UK after lawyers representing the Palestinian Islamist group Hamas sought to challenge the organization’s terrorist designation, prompting fierce criticism from British Members of Parliament and Jewish organizations.
Last week, Hamas filed a legal petition arguing for its removal from the United Kingdom’s list of proscribed terrorist groups, describing itself as “a Palestinian Islamic liberation and resistance movement whose goal is to liberate Palestine and confront the Zionist project.”
Riverway Law submitted a claim to UK Home Secretary Yvette Cooper on behalf of senior Hamas official Moussa Abu Marzouk, who also provided a witness statement in the case.
Given that accepting funds from Hamas would violate British law, the firm is providing pro bono representation to the terrorist group.
“The British government’s decision to proscribe Hamas is an unjust one that is symptomatic of its unwavering support for Zionism, apartheid, occupation, and ethnic cleansing in Palestine for over a century,” the filing reads.
“Hamas does not and never has posed a threat to Britain, despite the latter’s ongoing complicity in the genocide of our people.”
Hamas’s military wing, the al-Qassam Brigades, had been banned in Britain since 2001, but the Interior Ministry broadened the ban to include the group’s political entities in 2021, arguing that Hamas functions as a unified organization rather than separate branches.
“I would be very surprised if the British government agrees to remove Hamas from the proscribed list,” Jonathan Turner, chief executive of UK Lawyers for Israel, told The Algemeiner in an exclusive interview.
“The UK is not entirely sympathetic to Israel, but it’s still very unlikely they would rule in favor of Hamas.”
In applying for removal from the list of proscribed organizations, Turner explained that Hamas does not deny being a terrorist group but rather argues that it is undesirable for it to remain banned.
In its filing, Riverway Law outlines three primary grounds for why Hamas should be removed from the terrorist list.
The first argument contends that the UK’s ongoing proscription of Hamas violates international law, including the British government’s obligation not to be complicit in genocide, which Hamas claims is being perpetrated by Israel in Gaza.
Additionally, it highlights the UK’s alleged responsibility to end “the unlawful occupation of Palestinian territories,” referencing the 2024 International Court of Justice (ICJ) advisory opinion that Israel’s presence in Judea and Samaria and Jerusalem is illegal.
The second argument claims that proscribing Hamas violates the European Convention on Human Rights, particularly the rights to freedom of expression and assembly, as UK law prohibits the promotion or support of proscribed organizations.
Hamas argues that this ban restricts open debate on the Palestinian issue and peaceful demonstrations, while also being discriminatory since Israel is not similarly proscribed.
The third argument asserts that the proscription is disproportionate and not sufficiently justified.
Hamas argues that there is no direct threat to the UK, that its violence is a “legitimate response to occupation,” and that the proscription undermines Palestinians’ democratic will when they elected Hamas.

The terrorist group violently eliminated its Palestinian opposition in a brief conflict in 2007, when Hamas took full control of Gaza after winning legislative elections the prior year.
Turner countered that all three arguments lack merit, emphasizing that rights such as freedom of expression and assembly can be lawfully restricted under UK and international law to protect national security, public safety, and the rights or property of others.
He also pointed out that Hamas still holds 59 of the hostages abducted during its invasion of and massacre across southern Israel on Oct. 7, 2023, and that hostage-taking is a crime against humanity under international conventions.
“Hamas is a very vicious terrorist organization,” he told The Algemeiner.
Earlier this week, British Shadow Justice Secretary Robert Jenrick announced that he had reported Riverway Law attorney Fahad Ansari for supporting Hamas and jihad, as well as the firm’s potential breach of sanctions regulations.
“The legal profession is being damaged by ideologues exploiting their status to platform extremism,” Jenrick wrote in a post on the X social media platform.
“This isn’t about free speech. It’s about a man who repeatedly crosses the line into open support for terrorism — all while the authorities look away.”
Shadow Foreign Secretary Priti Patel also criticized the legal effort, calling Hamas an “evil Iranian-backed terrorist organization, which kidnaps, tortures, and murders people, including British nationals.”
More British citizens (18) were killed during the Hamas-led Oct. 7 onslaught than in any foreign terrorist attack since Al Qaeda struck the US on Sept. 11, 2001.
“They pose an ongoing threat to our security and to the peace and stability of the Middle East and have weapons and training facilities that put lives at risk and threaten our interests,” Patel said in a statement.
“They show no respect for human rights, life, and dignity and have oppressed people living in Gaza for too long.”
“Those campaigning to end the proscription of Hamas fail to understand the seriousness of the threats this terrorist organization poses,” the statement read.
Campaign Against Antisemitism (CAA), a UK-based Jewish civil rights group, also dismissed the case as a “bad-faith attempt to promote genocidal antisemitism,” rejecting the argument that proscribing Hamas stifles political engagement.
They argued that it’s still possible to campaign for Palestinian rights, criticize Israel, or support a two-state solution to the Israeli-Palestinian conflict without endorsing Hamas or terrorism.
Riverway Law’s legal challenge on behalf of Hamas came less than a month after a group of British lawmakers released a new and extensive report documenting the atrocities of the terrorist group’s Oct. 7 atrocities across southern Israel.
The report showed that, in total, about 7,000 Hamas-led Palestinian terrorists killed 1,182 people, wounded more than 4,000 others, and kidnapped 251 hostages — 210 living and 41 dead bodies at the time of their abduction — during the onslaught.
The study detailed Hamas’s planning, the weapons used, and the violence which occurred at each location, including gristly details of sexual violence, torture, and the desecration of corpses.
