It looks like Lozman is going forward. Arguments are scheduled for October 1st, and there is no indication from the Supreme Court that Lozman will be removed from the docket for a lack of controversy. In fact, in supplemental briefs requested by the Court, all parties agreed that the case should go forward because a controversy does exist, even though the structure at issue (a houseboat) was destroyed.
On SCOTUSBlog, reporter Lyle Denniston prepared a thorough and thoughtful write-up of the case. Why should the maritime community care about Lozman? As stated by Mr. Denniston:
The case will require the Court to spell out when a floating structure qualifies, legally, as a “vessel,” such that a dispute in which it is involved must be resolved in admiralty court under special rules of maritime law. The case has attracted the interest of the federal government, as well as of groups whose members make their living in marine industries, plus lawyers in the specialized field of maritime law, owners of houseboats, and even the operators of riverboat casinos. They all will be affected by how the Court defines “vessel.”
