Greenpeace activist Priya Pillai shows her passport on which airport officials stamped 'Offload'.
Greenpeace activist Priya Pillai on Tuesday moved Delhi High Court against her offloading from a flight to London at the Delhi airport recently.
Ms Pillai, who was offloaded from the aircraft by immigration officials on January 11, was scheduled to visit London to make a presentation before British MPs regarding alleged human rights violation at Mahan in Madhya Pradesh where a proposed coal mining project was threatening to uproot the lives of the local communities.
Greenpeace in a statement said that the activist has claimed that her being denied permission to travel abroad by government agencies was illegal and a violation of her basic right to personal liberty and freedom of speech.
It was also a "deliberate attempt to malign her reputation", it said.
