How often courts cite this section
Court decisions citing this, by year.Markers show enactment, consequential amendments, and circuit splits over this section — watch for a citation surge after a change or a disagreement. The dip in the last several years is a data-coverage gap, not a real trend — our corpus holds fewer opinions from the most recent years, so recent citations are undercounted.
Notwithstanding any other provision of law, the President, through the Attorney General, may authorize physical searches without a court order under this subchapter to acquire foreign intelligence information for a period not to exceed 15 calendar days following a declaration of war by the Congress.
