Rule of law:

In India, the longest constitutional text in the history of the world has governed that country since 1950. Although the Constitution of India may have been intended to provide details that would limit the opportunity for judicial discretion, the more text there is in a constitution the greater opportunity the judiciary may have to exercise judicial review. According to Indian journalist Harish Khare, "The rule of law or rather the Constitution [is] in danger of being supplanted by the rule of judges."
