Interestingly, the United Nations Human Rights Office's has quite the opposite opinion regarding the Evron vs. Donziger case (the one in the US that lead to Donziger's house arrest) [1].

"The Working Group recalls that it is inherent to the proper exercise of judicial power that it be exercised by an authority that is independent, objective and impartial in relation to the issues dealt with, as asserted by the Human Rights Committee in relation to article 9 (3) of the Covenant. In the present case, the Working Group is of the view that Judge P did not act in a manner which was independent, objective and impartial in relation to Mr. Donziger’s case. Consequently, the Working Group concludes that the imposition of pretrial detention upon Mr. Donziger was in violation of article 9 (3) of the Covenant. "
