In October 2022, she was appointed as the United Nations Special Rapporteur on the independence of judges and lawyers by the
Human Rights Council. This is a position that has existed since 1994. In September 2023, she had written in "alarm" to the
President of Kiribati. He had ordered that the Australian judge
David Lambourne who was married to the
leader of the opposition should be deported. The pilot had refused to take him, and the island's senior judges had all been suspended for refusing to enforce the President's will. This had left the country with no senior court of appeal or any legal check on the government's powers. In April 2024, she received a long letter from
Nagananda Kodituwakku who was a Sri Lankan lawyer and politician. He had been debarred from practicing law in 2019 following a dispute with a judge. He has asked Satterthwaite to intervene in the case which resulted in him being barred from practicing law. In 2024, she spoke out against the
plans of the United Kingdom to send immigrants to Rwanda while they apply for political asylum. The government was passing laws to override the judiciary. The new law would command judges to decide that Rwanda was a "safe country" irrespective of any evidence that was brought to the court. She said that the governments changes to the law "constitute an interference with the independence of the judiciary and a violation of international law". In June 2024, she was one of the many UN experts who spoke out against the sale of arms to Israel as a result of the
conflict in Gaza. The experts cautioned arms supplier and finance companies that they would be implicated in human rights violations. The list included special rapporteurs
