Just 51 per cent of registered Sliammon voters ratified the treaty last night, which gives the First Nation near Powell River, B.C., $30 million and more than 8,300 hectares of land.
Polak says while the vote was tight, it should still be considered a satisfactory result that allows the allows the Sliammon to start on the road to self government.
There were 615 members eligible to vote and with 318 people approving the treaty, the margin of victory was just 10 ballots.
But those who prevented the initial treaty vote on June 16 and made an unsuccessful attempt to get a court injunction stopping the vote say they are considering a legal challenge.
Brandon Peters, of the group Protectors of Sliammon Sovereignty, says his group is talking about disputing the final ratification vote based on voter-enrolment issues.
