The Queensland Police Service has executed a search warrant on the ABC in Brisbane, seeking leaked state Cabinet documents used in a series of news stories.

The police service sought the warrant in relation to a complaint by the Queensland cabinet secretary, Leighton Craig, that the documents may have been "improperly accessed" in breach of Cabinet rules.

The stories by ABC National Reporting Team journalists Mark Willacy and Alexandra Blucher focused on deep budget cuts to Queensland's environment department under the then LNP government of Campbell Newman in 2012.

The stories were based on a raft of leaked Cabinet briefing notes and internal savings proposals.

One Cabinet note revealed that the LNP government used a "pain ranking" to help decide which programs and budgets would be slashed, while another detailed how oversight of the controversial coal seam gas industry was repeatedly cut.

A third story in the series revealed the former Newman government killed off a profitable climate change company run by the state.

A police officer from the Queensland Police State Crime Command executed the warrant during a visit to the ABC's Brisbane office in South Bank.

The warrant said that a "person or persons unknown having been employed in public office by the Queensland Government unlawfully communicated information namely confidential cabinet briefing notes and internal government savings proposals by the Liberal National Party in 2012 … that was his or her duty to keep secret".
