In June, 2014 Gitxsan chiefs unanimously announced that they would discontinue discussions on all pipeline development on Gitxsan lands, due to the Crown illegally giving Gitxsan land to Tsimshian First Nation. The Gitxsan Nation claims strong prima facie rights and title to these territories since contact was made in 1846 [2, 10]See more...
Shortly after, Gitxsan First Nation Luutkudziiwus, Xsim Wits’iin and Noola chiefs declared that all natural-gas pipeline projects on their territory are prohibited, with a special reference to TransCanada Corporation’s Prince Rupert Gas Transmission Pipeline. The Rupert Gas Pipeline would cross Madii Lii territory over 32 kilometres. There is reportedly no interest in negotiating 
A press release on the Gitxsan Nation website traces the conflict back to a fraudulent consultation process beginning in September, 2012. (10) The Canadian government had offered 12 million CAD plus over 2 million CAD as a signing bonus in a letter to the Gitxsan Nation in return for allowing the Prince Rupert Gas Pipeline and the Westcoast Connector Gas Transmission Project to cross their territories. 
In July, eight Gitxsan hereditary chiefs issued an eviction notice calling for all loggers, sports fishers, and the Canadian National Railway to vacate the territory by August 4th, a deadline that was later extended to September 16th after Canadian Rail won an injunction pending a threatened Gitxsan blockade. 
Conflict also arose in May when several Gitxsan hereditary chiefs accused LNG and the Gitxsan Development Corporation of faking signatures of hereditary chiefs in approval of the LNG pipeline, when the chiefs in question were not aware that someone was signing on behalf of them 
Richard Wright, speaking on behalf of the house of Luutkudizii, stated that the formal notice barring pipelines from three Gitxsan chiefs issued to the B.C. government came as a response to ongoing negotiations between the government and Gitxsan Treaty Society (GTS) and Gitxsan Development Corp. The house of Luutkudizii is participating in a lawsuit that questions the validity of the GTS and its ability to speak on behalf of all Gitxsan people 
Wright pointed to particular environmental concerns, including the possibility of a pipe spill infiltrating creeks and the Suskwa, Bulkley River, and Skeena River, which would kill off salmon used for sustenance by the Gitxsan peoples . Other feared environmental impacts include the potential for LNG electrical power plants and subsequent reduced air quality .
Pacific NorthWest LNG, the proposed facility to liquefy and export the natural gas arriving via the Rupert pipeline, and Progress Energy Canada ltd., the producer of the gas, are both owned by PETRONAS, Malaysia's national oil company [3, 4].
The pipeline itself would transport gas from North Montney near Fort St. John, B.C. to the proposed liquefaction facility in Port Edward, near Prince Rupert, B.C.  Natural gas in North Montney is extracted via shale fracking (hydraulic fracturing) [6, 7].
