What is even more damaging is that these subsequently added words are now immortalized in Indian constitutional jurisprudence thanks to the Basic Structure doctrine, which makes them immune from challenge. If the Basic Structure is so sacrosanct, how did it permit the Preamble to be amended? A common explanation advanced is that this was permitted because these two words did not change the nature of the Constitution at all, but only explicitly expressed, what it already stood for. This is completely erroneous and as far from the truth as it gets.
