A Ballarat bus driver who was jailed for more than five years for seriously injuring six people when he crashed his bus into the notorious Montague Street Bridge has had a win in court.

Jack Aston has been granted leave to appeal his convictions.

The 55-year-old is serving a minimum 2.5 year jail term of the crash in February 2016.

Court of Appeal judges Phillip Priest, Stephen Kaye and David Beach have ruled there was a “substantial miscarriage of justice” in Aston’s County Court trial.

Mr Aston’s daughter, Meg, said she’s “really happy” about today’s developments.

“It’s a little bit of light,” she told 3AW’s Tom Elliott.

“Hopefully he doesn’t have to spend any more time in there.”

The hearing continues.
