An independent watchdog will investigate claims the Victorian public service has been stacked with Labor Party allies as part of a parliamentary referral.
In February, Victorian parliament passed a motion to call for the Victorian Ombudsman to re-investigate the so-called "red shirts" 2014 state election rorts scandal.
The motion, brought on by former Labor powerbroker Adem Somyurek, called for Deborah Glass to probe allegations "ALP activists are 'stacked' into the public service thus compromising objectivity and professionalism and increasing the risk of corruption".
AAP understands she will look into claims more than 30 senior public servants previously served as advisers in the Andrews government.
A week after the motion was passed, Ms Glass confirmed she would consider the referral and consult with the Independent Broad-based Anti-corruption, including on elements linked to their ongoing joint investigation into Labor branch stacking which centres on Mr Somyurek.
Upper house crossbench MP Clifford Hayes said he directly raised the alleged stacking of the public service with the ombudsman and was pleased she has launched an investigation.
"Make no mistake; politicising the public service is a form of corruption," he posted on social media.
