After reading Federal law, Doral can go to the U.S Supreme Court
Among the federal agencies with offices in Puerto Rico are: Internal Revenue Service; Small Business Administration; Veterans Affairs Department; Bureau of Tobacco, Alcohol & Firearms; Customs Service; Immigration and Naturalization Service; Drug Enforcement Administration; Federal Bureau of Investigations; Postal Service; Armed Forces; National Parks Service; Environmental Protection Agency; Fish and Wildlife Service; Department of Commerce; and others
As it does in the States, the federal government controls customs and immigration, interstate trade between Puerto Rico, the fifty states and other U.S. territories, licensing of radio and television stations, and regulates financial institutions, telecommunications companies, air and maritime common carriers and others.
Seven active judges, three senior judges and three magistrates nominated by the president of the U.S. and confirmed by the U.S. Senate, serve on the U.S. District Court for the District of Puerto Rico. Its decisions may be appealed through the federal court system to the U.S. Court of Appeals for the First Circuit, and on to the U.S. Supreme Court. Decisions of the Puerto Rico Supreme Court may be appealed directly to the U.S. Supreme Court. Also present on the island is the U.S. Bankruptcy Court.
I think you have it backwards. DRL is winning every battle in court. PR blatantly violated the agreement and made up "legal" justifications to try and justify a political decision. I assume DRL will win in court. The problem is that PR can then still appeal further as you've pointed out. This illustrates why DRL shareholders desperately need PR to settle voluntarily (no appeal). Unfortunately I doubt we're going to get a settlement. I guess it's good politics to go after those "Wall St. Millionaires". If you own a few shares of DRL, guess who that is.
Shareholders don't desperately need a settlement. Impatient people desperately need a settlement. Given the way things have been going, seems it's either a near term win or a medium term win for DRL, regardless.
