The preamble is indeed not enforceable in a court of law - it is non-justiciable, meaning courts cannot directly enforce it or give remedies based solely on the preamble. However, the preamble contains a typo: 'court of low' should be 'court of law'. Courts can use the preamble as an interpretive aid to understand the Constitution's basic philosophy when there is ambiguity in constitutional provisions. The preamble has only been amended once (42nd Amendment, 1976), not twice.
