A convicted murderer in Victoria, Australia, is taking legal action against the state’s prisons commissioner in a bid to regain access to Vegemite, arguing the iconic spread is part of his cultural identity.

Andre McKechnie filed the complaint insisting that being denied Vegemite violates his right to “enjoy [his] culture as an Australian,” according to court documents.

The inmate claims the ban deprives him of a basic cultural practice.

Vegemite has been prohibited in Victoria’s correctional facilities since 2006 due to concerns that the yeast-rich spread could be used to create improvised alcohol, commonly referred to as “pruno” or “hooch.”

McKechnie’s legal argument draws on Victoria’s human rights charter, which states that individuals must not be denied the opportunity to engage in their culture.
