In a court case 40 years ago (1984), the Chevron doctrine was established. Once passed, it meant that all cases in the future needed to rely on decisions made by agencies responsible for expanding and interpreting laws set up by Congress when there were no precise instructions on what to do.
Congress often left the “nitty-gritty” details of new laws to be decided by other governmental organizations. On June 28, the Chevron doctrine, which formed the basis of cases since it was made, was set aside. Until the Loper Bright case, cases were often decided based on the interpretation of laws made by the various agencies that dealt with a particular set of laws—even when their regulations were not precise.
