Lawyers for WikiLeaks founder Julian Assange sued the US Central Intelligence Agency and its former director Mike Pompeo on Monday, alleging it recorded their conversations and copied data from their phones and computers.
The attorneys, along with two journalists joining the suit, are Americans and allege that the CIA violated their US constitutional protections for confidential discussions with Assange, who is Australian.
Assange is facing extradition from Britain to the US, where he is charged with violating the US Espionage Act by publishing US military and diplomatic files in 2010 related to the Afghanistan and Iraq wars.
Robert Boyle, a New York attorney representing the plaintiffs in the lawsuit, said the alleged spying on Assange's attorneys means the WikiLeaks founder's right to a fair trial has "now been tainted, if not destroyed."
"The recording of meetings with friends, with lawyers and the copying of his attorneys' and friends' digital information taints the criminal prosecution because now the government knows the contents of those communications," Boyle told reporters.
"There should be sanctions, even up to dismissal of those charges, or withdrawal of an extradition request in response to these blatantly unconstitutional activities," he said.
The suit was filed by attorneys Margaret Ratner Kunstler and Deborah Hrbek, and journalists Charles Glass and John Goetz.
The suit named the CIA, former CIA director and former US secretary of state Pompeo, and the security firm Undercover Global and its chief executive David Morales Guillen.
It said Undercover Global, which had a security contract with the embassy, swept information on their electronic devices, including communications with Assange, and provided it to the CIA.
In addition it placed microphones around the embassy and sent recordings, as well as footage from security cameras, to the CIA, the suit alleges.
This, the attorneys said, violated privacy protections for US citizens.
Assange is awaiting a ruling on his appeal of the British extradition order to the United States.
The charges he faces could bring a sentence of up to 175 years in prison.
- Pompeo 'approved' the spying -
The suit said that Spain-based Undercover Global was recruited to work with the CIA in 2017 by officials from the Las Vegas Sands casino group.
Las Vegas Sands was at the time controlled by the late tycoon Sheldon Adelson, a powerful conservative backer of the Republican Party who, the suit said, "had cooperated with the CIA on similar matters in the past."
The suit said that while Undercover Global controlled security at the embassy, each visitor had to leave their electronic devices with a guard before seeing Assange.
"The information contained on the plaintiff's devices was copied and, ultimately, given to the CIA," they said.
"Defendant Pompeo was aware of and approved the copying of information contained on plaintiffs' mobile electronic devices and the surreptitious audio monitoring of their meetings with Assange," the suit alleged.
It said the defendants became aware of the spying only when the Spanish newspaper El Pais reported in September 2019 that Morales and Undercover Global were under criminal investigation in Spain.
El Pais revealed information on the London operations that had previously been sealed in the case.
