Final answer:
Alexander Hamilton described the judiciary as 'the least dangerous' branch of government in Federalist No. 78, emphasizing its role of judicial review despite its lack of force or financial power.
Step-by-step explanation:
In Federalist No. 78, written by Alexander Hamilton, the judiciary is described as being 'the least dangerous' branch of government. This view is based on the judiciary's nature and function, particularly its incapacity to wield force or wield the national purse. Although considered the weakest branch, Hamilton emphasized the important power of judicial review held by the judiciary, which allows them to interpret the Constitution and ensure that laws are in accordance with it. Over time, discussions have ensued about whether the power of the Supreme Court has become too large, shifting from being 'the Least Dangerous Branch' to what some call an 'Imperial Judiciary.'
