Courts may use a burden-shifting process to sift through evidence presented by the parties.
The most well-known burden shifting process is the “McDonnell Douglas Framework.” The Supreme Court created the method in a case brought by a black employee against his employer (McDonnell Douglas Corp. v. Green, 1973). Percy Green worked for the aircraft manufacturer McDonnell Douglas Corporation. He alleged McDonnell Douglas refused to rehire him because of his race. The McDonnell Douglas Framework is outlined in this infographic.
Today, courts use burden-shifting frameworks for various types of legal claims. See a Supreme Court case of this term that incorporates a burden-shifting framework: Ohio v. American Express.
