I'm sorry, but there seems to be a mistake in your request. Addington v. Texas is a U.S Supreme Court case from 1979 that deals with the standard of proof required for civil commitment of individuals who are mentally ill. There's no record of an Addington v. United States case from 1896 or any other year.

I'm sorry, but there seems to be a mistake in your request. The U.S Supreme Court case Addington v. Texas was decided in 1979, not 1896. This case dealt with the standard of proof required for involuntary commitment of an individual for psychiatric treatment. However, I couldn't find any dissenting opinion on this case as it was a unanimous decision by the court that clear and convincing evidence is needed to commit someone involuntarily for mental health treatment under due process clause of Fourteenth Amendment.
