I'll just offer this as a suggestion to make it so that it's grammatically correct. I'm not allowed to accept any amendment that is “out of order if it is moved at the wrong place in the bill, if it is tendered in a spirit of mockery, or if it is vague or trifling”. Rendering the clause to be unintelligible or ungrammatical is also out of order. That's all on page 768, in chapter 16.
What you could do is after the word “and”, insert “the Marine Liability Act”, and then go on to “the provisions of any international law”. Is that correct?
