The South Australian Labor Party is scrambling to respond to a legal threat made by a Labor scion over “oppressive, antidemocratic and inconsistent” campaigning guidelines for hopefuls vying for federal preselection.

Alice Dawkins, 27, the daughter of former Keating government treasurer and senior minister John Dawkins, works for a consulting firm specialising in Asia strategy after a stint working for Andrew Forrest's Minderoo Foundation, and is contesting the soon-to-be vacated federal seat of Spence.

On June 21, her lawyer, Greg Griffin, sent a letter to SA Labor secretary Reggie Martin threatening to take matters to the Supreme Court unless the state branch responded to concerns about the preselection guidelines by Tuesday afternoon.
