In November 2014 Art Dula, Dula's law office associate Anat Friedman, his business partner J. Buckner Hightower, The Robert A. and Virginia Heinlein Prize Trust, Excalibur Limited, Excalibur Almaz Limited and Excalibur Almaz USA Inc were all sued by Japanese entrepreneur Takafumi Horie for fraud. The amount mentioned was $49 million, allegedly provided by Takafumi to run the company. It is alleged that some of the money was spent to buy Soviet hardware, which, as the businessman states, turned out to be "museum specimens". Some of the money was also transferred into Dula's own name. Other alleged irregularities included reducing Takafumi's shareholding percentage.
