But companies can avoid those rules, too. Two-thirds of ships carrying Russian oil – the trade of which is restricted by the U.S. and other countries – reportedly have “unknown” insurance providers, meaning nobody knows whom to call to cover the cleanup costs after a spill or collision. The enforcement mechanism works until ship owners realize they can just opt out of it entirely, using less reputable ports or transferring oil from ship to ship out at sea.

^ This very thin sense of “duty” has been characterized using various terms. See Victor Tadros, Beyond the Scope of Consent, 50 Phil. & Pub. Affs. 430, 434 (2022) (“fact-relative dut[ies]”); Gardner, supra note 39, at 142 (“obligations to succeed” (footnote omitted)); Goldberg & Zipursky, supra note 6, at 113 (“dut[ies] of noninjury”). Because fact-relative duties cannot guide an agent’s behavior (at least not directly), and violating them does not render an agent open to criticism or blame, it is controversial whether they should be understood as genuine duties at all. For thoughts along these lines, see T.M. Scanlon, Moral Dimensions: Permissibility, Meaning, Blame 47–52 (2008).
