The National Court in PNG has accepted arguments that the marine dumping of toxic waste from the Ramu nickel mine will breach PNG's Constitution and constitute both a public and a private nuisance.

ACT NOW! has been campaigning against the marine dumping of mine waste in PNG and in October 2010 over 500 ACT NOW! supporters participated in an email action against Highlands Pacific, part owners of the Ramu mine.

Although the National Court refused to permanently restrain the marine dumping that decision is now being appealed to the Supreme Court.
