Seems the right way to understand this is that Liberty Star and Northern Dynasty filed suit against MBGS LLC, and MBGS counter-sued. A typical response.

There are some posters who present this simply as a case filed against Liberty Star. They seem to want readers to think that the company probably did something wrong. I disagree.

Liberty Star filed suit first -- against MBGS. In response to a lien filed by MBGS, reason no clear yet. Could be an unjustified attempt to get a payoff of some kind. Maybe a legitimate confusion over terms of a contract and payments made or not made.
