Ukyo will not go near a lawyer. Lawyers go to court and the last place Ukyo wants to end up is in a courtroom.

Let's get this clear - Ukyo is a multi-million dollar fraudster and thief. He will be going to prison if he is caught.

Now do you really want hundreds of BTC worth of shares to go back to him? He has all the reasons in the world to sell them and run away to Mexico.

The ACtM shares have been seized under lien, the basis for which is US Contractual and Corporation law. The CEO of ACtM has taken control of the shares and has listed them on an exchange for 0.01BTC per share.
Only 5% of them need to be sold at that price to fully cover all of the ACtM debt.
Once that debt is settled the remaining shares or BTC will likely be given to a safe third party for distribution to the victims of Uyko. This is entirely legal and right. It is also the best hope you have of getting any money back.

Remember these shares only hold any value for you  if the company ACtM is a success. If you sue ACtM, you will be suing yourself because if ACtM fails or is crippled by your court case then the shares will be worthless on the open market - no one will buy them at premium if the company is being dragged through the courts.
