s 26 Protection of informers
26.—(1) No witness in any proceedings for an offence under section 5 or 6 is obliged or permitted to disclose the name or address of an informer or the substance of the information received from the informer or to state any matter which might lead to the informer’s discovery. (2) If any document which is in evidence or liable to inspection in any proceedings contains any entry in which any informer is named or described or which might lead to the informer’s discovery, the court must cause the entry to be concealed from view or to be obliterated so far only as may be necessary to protect the informer from discovery. (3) If, during any proceedings —(a) the court, after full inquiry into the case, believes that the informer wilfully made in his or her complaint a material statement which he or she knew or believed to be false or did not believe to be true; or (b) the court is of the opinion that justice cannot be fully done between the parties to those proceedings without the discovery of the informer, it is lawful for the court to require the production of the original complaint, if in writing, and permit inquiry, and require full disclosure of the informer.
