Claims that the Independent Commission Against Corruption engaged in "judge shopping" to obtain search warrants have been dispelled by a document showing NSW law enforcement agencies are required to use the same registrar.

ICAC was accused by a media report of using the same registrar 10 times to authorise raids on the home of Crown prosecutor Margaret Cunneen, SC, and NSW Liberal politicians including former energy minister Chris Hartcher.

The report alleged this raised questions about whether ICAC is judge shopping.

But a protocol established in 2014 requires law enforcement agencies, including ICAC and the Police Integrity Commission, to contact the same person, Stephen Lister, to obtain search warrants.
