According to Last Free Voice:
The Libertarian Party (Libertarian National Committee, Incorporated) is apparently preparing to file suit against the New Hampshire Secretary of State. The lawsuit will demand that the state place Bob Barr on the ballot, and remove George Phillies from the ballot. This suit is separate and distinct from the ACLU lawsuit in Massachusetts to substitute Bob Barr in place of George Phillies on the Massachusetts ballot.
The article claims that Phillies is not cooperating with efforts to remove him from the New Hampshire ballot, reportedly citing an ethical obligation to petition signers that placed him there.
Barr is expected to appear on the New Hampshire ballot as well, since his supporters submitted what they believe is enough signatures to qualify in the state appart from seeking to replace Phillies.
