Due Process of Law in the United States Judicial Review

14th amendment of the United States constitution, established the “Due Process” clause to create an effective way for protecting fundamental rights and freedoms against all government authorities’ actions through judicial review by courts. Thus, in case of violation, legislative or executive measures subject to complaint will be null and void. This Paper sheds light on the mechanisms and frameworks of applying this principle in the United States judicial review, explaining how the U.S legal system guarantees the citizenship rights; it is an effective step for future legislation and legal practice to guarantee “peoples’ rights” set forth in the constitution of the Islamic Republic of Iran.
