The Blue Jacket v. The Tacoma case in 1891 revolved around a collision between two vessels, the British ship "Blue Jacket" and the American steamer "Tacoma". The incident took place off Cape Flattery, Washington. Both ships blamed each other for not following navigational rules leading to the accident. After deliberation, the U.S Supreme Court held that both vessels were at fault - with Tacoma failing to maintain a proper lookout and Blue Jacket neglecting to signal its course properly. Consequently, damages from the collision were divided equally between both parties as per maritime law principles of shared responsibility in such incidents.

The dissenting opinion in the case of The Blue Jacket; The Tacoma, 1891 was not explicitly stated or recorded.
