For over three months, construction work had stopped as protestors, said to be led by mostly Catholic priests, had reportedly erected a large shelter blocking its entrance, saying the port's development had caused coastal erosion and deprived them of their livelihoods. Fisherfolk and priests, including the archbishop of the Latin Archdiocese of Trivandum have been charged with attempt to murder, rioting, trespass, criminal conspiracy and obstructing public servants from carrying.
However, a local people’s action committee has extended support to the Adani project. It has political backing from BJP and CPI(M), and moral support from Hindu outfits like the upper caste Nair Service Society, Sree Narayana Dharma Paripalana Yogam, and Vaikunda Swami Dharma Pracharana. Senior CPI(M) leader and state education minister V Sivankutty has blamed the Latin Catholic Church. BJP state president K Surendran said that the Latin Catholic diocese of Tuticorin that had organised the protest against the Kudankulam nuclear power plant near Kanyakumari in Tamil Nadu, were behind the Vizhinjam protest.
