The decision by the Kuria revised the rulings of two lower courts that had sentenced Petra Laszlo to three years' probation for disorderly conduct.

The Kuria said Ms Laszlo should have been charged with a misdemeanour instead of a criminal offence.

It said the case had to be terminated now since the statute of limitations had expired.

In September 2015, Ms Laszlo was filming asylum seekers passing through Hungary on their way west when several broke through a police cordon and jostled her as they ran by.

She responded by kicking two people, including a young girl.

Laszlo 'wall of shame' archives community outrage

When news broke the footage, internet commentators were quick to denounce Ms Laszlo's actions.

A "Petra Laszlo Shame" wall began in earnest on Facebook, gathering over 30,000 likes at its peak (currently it has just over 1,000 likes).

Some of the sentiments shared on the page simmered with misogyny in addition to expressions of disgust.

"Nothing left to say — a person like her should never ever be allowed to report about anything again," user Ahmend Elsayed Omar said.

In an interview with Russian news service Izvestia at the time, Ms Laszlo said she planned to sue Facebook for failing to remove threatening comments and messages aimed at her.

She also planned to sue Syrian Osama Abdul Mohse, one of the asylum seekers she kicked, alleging false accusations.

So far there has been no record of a case being brought against either party.

'I'm not a heartless, child-kicking racist'

In a letter published in Hungarian newspaper Magyar Nemzet, Ms Laszlo expressed her regret at her behaviour.

"As I watch the footage now, it's like I'm not watching myself," she said.

"I honestly regret what I have done and take responsibility for it.

"I panicked. I'm not a heartless, child-kicking racist cameraperson.

"I was afraid as they were rushing toward me and then something snapped in my head."

After the incident, Ms Laszlo was fired from her job as a camera operator at N1TV, a internet-based television service closely linked to Hungary's far-right Jobbick party.
