A mother who assaulted a paramedic has run from court after being spared jail.

Amanda Warren, 33, and Caris Underwood, 20, had the jail sentences they received for assaulting paramedic Paul Judd in 2016 quashed on appeal by Victoria County Court judge Barbara Cotterell on Tuesday.

Warren and Underwood were originally sentenced to six months and four months respectively, but Judge Cotterell said special reasons linked to their difficult childhoods and young families mean the minimum six-month term should not apply.

The women admitted punching and kicking Paul Judd as he and another paramedic tried to treat a patient in Reservoir.

Lawyers for both women say the pair had tough childhoods but have started to turn their lives around since their drunken assault.

They both pleaded guilty last year to intentionally causing injury, while Warren has also admitted to criminally damaging the ambulance by ramming it with a car.

Mr Judd broke his foot in the violent attack and has required multiple surgeries since.

The experienced ambulance worker has not been able to return to work since the violent attack in April 2016.

Unless there are 'special reasons', Victorian laws introduced in 2014 demand a mandatory minimum jail term of six months for anyone who intentionally injures an emergency worker.
