I think this is overselling the stability of the judicial process in the UK, US and other countries with a strong grounding in the rule of law. Without getting to political, sometimes judicial controversies spring up in the US. The issue is there are centuries of norms to fall back on. India doesn't have that yet - they have millennia of history in being the centre of civilisation but not in how the current legal system should be applied under the governance of the sweaty masses of voting Indians.
India is going to be more politically dynamic than the US at the moment because it is bigger and its ability to direct itself democratically is a bit younger. So judges are going to be harder to predict regardless of how strong the rule of law is - there is effectively less data even assuming a perfect rule of law.
