perhaps this is a stupid question but i do not understand why DAN is suing ?
This is a pure guess since I don't want to pay to read the filing, but what would make sense is that Bottoms Up had a current insurance policy through DAN. However when DAN got pulled in on this case, they went through Bottoms Up's insurance application and found the alleged lie. So now they are asking the court to either make a legal determination that the insurance contact was invalid from the start or they are asking the court for a ruling that Bottoms Up must repay DAN for anything it has to pay out to cover claims arising while the policy was in effect.
Here you go. Lots of very interesting tidbits.
