One of Stevens' biggest -- the 2002 Bush vs. Gore case, in which the Supreme Court effectively put Bush in office. Stevens wrote a dissenting opinion, saying the majority's ruling undermined the people's faith in government and the courts.  

Another big decision ... his dissent in the Citizens United case, which opened up campaign finance donations from wealthy individuals and corporations.

Stevens was a gun control advocate, once writing a dissenting opinion in which challenged the majority's decision to a major gun control law. In 2018, years after Stevens retired, he publicly challenged the Court's reading of the 2nd Amendment in the wake of the Stoneman Douglas High School massacre, saying it was a "relic of the 18th Century."

Stevens served as a Lt. Commander in the Navy in World War II and was awarded a Bronze Star and the Presidential Medal of Freedom.

Before joining SCOTUS, President Nixon appointed Stevens in 1970 to the 7th Circuit Court of Appeals.
