The 9th Amendment simply states that rights may be given to citizens of the United States even if they are not explicitly afforded in the Constitution.
The only case I could find relating to the 9th Amendment was Griswold v. Connecticut. This case is only loosely related though because the majority opinion, written by Justice Douglas, mentions the 9th Amendment but does not relay on it for the rationale. Justice Goldberg in his concurring opinion, expounds greatly on the meaning, past history and James Madison’s intentions in including the 9th Amendment in the Constitution.
