Yes, there have been court cases and judicial decisions interpreting the concept of "office of profit under Government" and its impact on parliamentary membership. One such notable case is Kihoto Hollohon vs Zachillu & Anr (1992). The Supreme Court in this case laid down the principles for determining disqualification under Article 102(1)(a) of the Indian Constitution.
