Section 129

If any book, document or paper which is in evidence or is liable to inspection in any civil or criminal proceedings contain any entry in which any informer is named or described or which might lead to his discovery, the court shall cause all such passages to be concealed from view or to be obliterated so far only as may be necessary to protect the informer from discovery.

If on the trial for any offence under this Ordinance the court after full inquiry into the case believes that the informer wilfully made in his complaint a material statement which he knew or believed to be false or did not believed to be true, or if in any other proceedings the court is of the opinion that justice cannot be fully done between the parties thereto without the discovery of the informer, it shall be lawful for the court to require the production of the original complaint, if in writing, and permit inquiry, and require full disclosure, concerning the informer.
