Ten Greenpeace activists forced a ship carrying Russian diesel to U-turn to highlight “state-level hypocrisy”, a court has heard.
The defendants were said to have blocked a jetty at the Navigator Terminals in Grays, Essex, in May.
They have gone on trial at Chelmsford Magistrates’ Court, where they denied obstructing or disrupting a person engaged in a lawful activity.
Prosecutor Monali Raleraskar said the jetty was “important” to the terminal.
“They had gained access from the riverside by dinghy boats,” she said.
