Wrong. The very language you underlined is all talking about the role courts play in Maritime Law. It is not saying that Maritime Law is the same law that applies to events on land.
Do you not speak English? Because anyone who does should realize that language does not mean what you claim. FFS.
OMG. I. Am. Deceased. You realize that says that the federal courts INTERPRET maritime law, right? Not that they operate under maritime law?
It’s amazing how people can completely misunderstand basic English. It’s not like there is any legal-ese in that portion. Plus it has to be interpreted in light of what the definition is above.
