The Globe and Mail reports in its Thursday, Jan. 12, edition that Enbridge may be set for a legal battle in Wisconsin after a native American tribe voted against renewing land-use agreements on a major crude oil pipeline. A Reuters dispatch to The Globe reports that the vote last week has ratcheted up tension on Enbridge. The decision also opened a new avenue of opposition to North American energy infrastructure, as it was a notable use of tribal authority to move against an existing pipeline. The Bad River Band decided that Enbridge should no longer be allowed to operate the Line 5 pipeline across its reservation, and is calling for the 64-year-old conduit to be removed because of concerns about potential oil spills. Line 5 is a vital part of Enbridge's Mainline system, which transports the bulk of Canadian crude exports to the United States. Enbridge says it is reaching out to the band to restart negotiations while also evaluating its long-term strategy. Legal experts say that if negotiations fail, Enbridge is unlikely to be able to have state or federal authorities force the band to allow Line 5 to operate, a process known as condemnation, if it is on tribal lands.
