What remains of the Houghton Mifflin Harcourt Publishing Co. reorganization was sent yesterday to the U.S. Bankruptcy Court in Boston, Bloomberg News reported on Friday. The bankruptcy judge in New York, where the prepackaged Chapter 11 petition was filed on May 21, ruled on June 22, the day after he signed a confirmation order, that the case was improperly filed in New York. The judge said he would send the case away officially when the reorganization plan was implemented. There will be no further proceedings in New York. As a result, the bankruptcy judge in Boston, where the company is based, will rule on professionals' fee requests.
