In griswold v. connecticut, on what did justice goldberg base his concurring opinion?

By a 7–2 majority, on June 7, 1965, the Supreme Court concluded that the Connecticut statute was unconstitutional. ... Justice Arthur Goldberg wrote a concurring opinion in which he used the Ninth Amendment in support of the Supreme Court's ruling, reasoning that the right of privacy was retained by the people.

Hope this helps!
Good day to you.
