Lawyers for Evangelos Pistiolis-led Top Ships are redoubling their efforts to persuade a judge to throw out a securities fraud lawsuit over the shipowner’s dealings with Kalani Investments.

The case is one of three shareholder lawsuits focused on financing of Greek shipowners by Kalani, a firm based in the British Virgin Islands and controlled by Toronto-­based Marc Bistricer and his hedge fund, Murchison Ltd.

Top Ships’ lawyers are seeking to have claims against the New York-­listed company thrown out with prejudice, asking the court to bar any further amended complaints.
