A SELF-proclaimed witch who says she is not subject to earthly laws is appealing against convictions for dangerous driving and recklessly causing injury.

She was sentenced to jail after pleading guilty to dragging a traffic policeman by the arm for 190m.

Highton marriage celebrant Eilish De'Avalon told Sen-Constable Andrew Logan in February last year she was not subject to earthly laws because she was from another world.

"Your laws and penalties don't apply to me. I'm not accepting them, I'm sorry, I must go, thank you," De'Avalon said.

De'Avalon, 41, was jailed for two months in August with another four months suspended, but was granted bail after lodging an appeal against the sentence and conviction.

She was also fined $1250 and her licence was disqualified for one year.

Geelong Magistrates' Court heard Sen-Constable Logan feared for his life during the ordeal in which his arm was pinned inside the car.

He said De'Avalon ignored repeated calls to stop and instead accelerated up to 60km/h.

When the car slowed in traffic, Sen-Constable Logan was able to grab the keys from the ignition.

He suffered a torn pectoral muscle and damaged shoulder and arm ligaments.

De'Avalon's lawyer David Hone said she had reacted involuntarily.

The appeal is listed to be heard by Judge Geoffrey Chettle in the Geelong County Court at 10am today.
