In the case of Clinton v. Jones (520 U.S. 681 (1997)), President Clinton claimed that, as a sitting President, he could not be sued for civil litigation unrelated to his office. However, the Supreme Court found that a sitting President has no immunity from civil law litigation against him, for facts unrelated to his office (having occurred before he took office). The Court ruled that separation of powers does not mandate that Federal Courts delay all private civil lawsuits against the President until the end of his term of office. In his concurring opinion, it was argued that presidential immunity would only apply if the President could show that a private civil lawsuit would somehow interfere with the President's constitutionally-assigned duties. "It appears to us highly unlikely to occupy any substantial amount of petitioner's time." Considering the result of the suit, it can probably be argued by future Presidents that this sort of civil litigation will interfere with their duties.
