How often courts cite this section
Court decisions citing this, by year.Markers show enactment and consequential amendments — watch for a citation surge after a change. 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.

Such proclamation shall immediately be transmitted to the Congress and published in the Federal Register.

No law enacted after September 14, 1976, shall supersede this subchapter unless it does so in specific terms, referring to this subchapter, and declaring that the new law supersedes the provisions of this subchapter.
