Sakto Corporation, a Canada-based company run by Jamilah Taib Murray and her husband Sean Murray, is seeking an injunction against Swiss-based NGO Bruno Manser Fund (BMF).
BMF had been at the forefront of scrutinising the wealth of Sarawak governor Abdul Taib Mahmud, who is Jamilah's father, amid accusations that he had amassed a vast amount of wealth during his 33-year stint as the state's chief minister.
Sakto, in a statement released through public relations firm GRA Communications, said the application for an injunction was filed at the Basel Civil Court in Switzerland.
"The injunction seeks to order BMF to remove from the public domain a litany of false statements and speculative allegations relating to Sakto.
"These total over 1,100 infringing statements and over 250 publications. The injunction also seeks to prevent BMF from repeating the defamatory comments," it said in the statement.
Sakto said the impression that BMF had created was "wrong and damaging" against the company's reputation and business.
It noted that since 2010, the NGO had filed and sent 11 complaints and letters across six jurisdictions with various authorities in relation to the company.
Sakto denied the allegations, calling them "untruthful theories about Sakto presented as facts".
Last year, BMF produced an 86-page report titled "Safe Haven Canada", detailing Taib's alleged business empire in the country.
