Which one of the following statements with regard to the Preamble to the Constitution of India is not correct?

Statement 4 is incorrect because the Supreme Court has consistently held that the Preamble serves as a key to the minds of the Constitution's makers and can be used as an aid to interpretation when the language of an article is ambiguous or capable of multiple meanings [3]. Statement 1 is correct as the words 'Socialist' and 'Secular' were added by the 42nd Amendment Act in 1976; originally, the phrase was 'Sovereign Democratic Republic' [2]. Statement 2 is correct because the Kesavananda Bharati case established that the Preamble contains basic elements or fundamental features that form the 'basic structure' of the Constitution [2]. Statement 3 is correct as the Preamble is non-justiciable and not enforceable in a court of law. Therefore, the assertion that the Court rejected the Preamble as an interpretive aid is false.
