A Japanese billionaire has filed a fraud lawsuit against Houston attorney and his law firm, alleging the lawyer took $49 million from him to start a private space flight project that never got off the ground.

The lawsuit, Takafumi Horie v. The Law Offices of Art Dula, which was filed Nov. 10 in a Harris County district court, alleges that attorney Art Dula convinced Takafumi Horie that he could set up a commercial space transportation program to carry people and cargo into a low Earth orbit by using Russian-made Almaz class space craft.
