Outside the court after the dismissal, Mr Grant said: “Justice and common sense prevailed in court today, but that hasn’t been the case for many activists recently.
“We have become a country that regularly sends peaceful protesters to jail, with some facing years behind bars for trying to preserve a habitable planet for us all.
“This has to stop.”
A trial was held after they each pleaded not guilty to a single count of causing criminal damage to 15 of the tiles on the roof of the house.
The activists also draped one side of Mr Sunak’s home in black fabric, with a sign that read “No New Oil”.
Mr Sunak was on holiday with his family in California at the time and the activists were found by members of staff who were staying at the house.
Back in July as the prosecution closed its case during the trial, defence lawyer Owen Greenhall submitted that there was no case to answer because it could not be proved the roof damage was caused during the protest.
The trial also heard from Malcolm Richardson, a foreman and roofer who had a contract to carry out work at the house, who was asked to check the roof after a police officer investigating the protest said he believed there had been some damage caused.
