Where an appeal is lodged against an order other than a settlement order or where the case is referred directly to the Investigating Chamber, pursuant to Articles 81, ninth paragraph, 82-1, second paragraph, 156, second paragraph, or 167, penultimate paragraph, the investigating judge shall continue his investigation, including, where applicable, until the case is settled, unless the president of the investigating chamber decides otherwise. This decision is not subject to appeal.
The same applies when the investigating chamber receives a request for nullity pursuant to Article 173.
