An enormous potential roadblock has been revealed in the question surrounding David Warner's leadership ban being overturned.

Warner is one of a number of names who has been floated as a potential option to take over the captaincy of the ODI team, following the resignation and retirement from the format of Aaron Finch.

The 35-year-old has openly admitted he expects Test captain Pat Cummins to take over the job, however, Cummins himself has suggested the workload may be too much for a quick bowler.

Mitchell Marsh, Steve Smith and Alex Carey have been the other names put forward as potential options to lead Australia with an ODI World Cup just 12 months away.

The Sydney Morning Herald have revealed however that Warner may be unable to have his leadership ban overturned under Cricket Australia's official code of conduct documentation.

In the aftermath of the 2018 Cape Town ball tampering scandal, Warner was hit with a lifetime leadership ban, while Steve Smith was banned for 12 months following his return to play. Warner and Smith were banned for 12 months from playing as well, while Cameron Bancroft copped a nine-month ban.

Warner, Smith and Bancorft all gave up their rights to a hearing over the issue however, which also means they have, under Cricket Australia's rules, given up their right to appeal any of the sentences down the track, as Warner now is in a position to do.

It's understood Cricket Australia have been open to the idea of discussions with Warner, and even potentially reversing the ban with a new board elected now, however, there are concerns that changing the code of conduct could open up the governing body to issues down the track.

It's unclear at this stage if the Cricket Australia board would be willing to issue a rewrite of the code of conduct, while overturning th ban would also likely require a new investigation into the issues of Cape Town.
