Ms Morris-Evans, who is a co-founder of Extinction Rebellion Jews, and Ms Ditchfield said they were motivated to carry out the protest by GCM’s plans to dig a coal mine in Bangladesh, which they said would cause loss of life and contribute to the climate crisis.
The pair were convicted of criminal damage, given conditional discharges and ordered to pay court costs and victim surcharges totalling £370 each at City of London Magistrates’ Court in October 2019.
But they appealed against their convictions at Southwark Crown Court on the grounds that they had not intended to cause the damage.
They argued the damage they caused did not meet the legal definition of “criminal damage”.
However, a judge said their appeal was based upon a “fundamental misconception” of the law.
