According to an excellent source, the New Hampshire ballot lawsuit has been authorized by Libertarian National Committee Chair Bill Redpath, and will be filed in the morning (Friday 8/29).
As previously discussed, the lawsuit is expected to seek the removal of George Phillies from the ballot, and the placement of Bob Barr on the ballot. New Hampshire ballot law does not allow for substitution, and George Phillies is currently the LPNH presidential nominee.
Professor Phillies is already ballot-qualified, according to the New Hampshire Secretary of State. However, Professor Phillies says he will not step down, because he feels he has an ethical obligation to those who signed the petitions placing him on the ballot.
LFV will update as more information becomes available.
