Sacked school dinner lady Carol Hill won the latest stage of her case against unfair dismissal today.
Ms Hill's union Unison said she was now in line for compensation after a two-year battle.
She was sacked from Great Tey Primary School near Colchester in 2009 after telling a parent she had found her daughter tied to a fence with whip marks to her legs.
An employment tribunal found two years ago that she had been unfairly dismissed but added later that she had contributed to her dismissal, so her compensation would be reduced.
Unison said that the employment appeal tribunal had upheld all grounds of appeal, so the level of compensation must be considered again.
Ms Hill said: "I am delighted with the outcome. This appeal has never been about money, but about protecting the children in my care and my right to speak out about what I witnessed at school that day."
