Fundamental Rights vs Legal Rights vs Constitutional Rights

It's easy to conflate "rights" of different constitutional weight, and exams frequently test the distinctions precisely because they matter for remedy and amendability.

• A legal (or statutory) right is one created and protected by an ordinary law passed by Parliament or a State Legislature — e.g., the right to a minimum wage under the Minimum Wages Act, or the right to property under Article 300A after 1978. Parliament can amend or abolish a legal right through ordinary legislative process (a simple/special majority as the case may be), and its violation is remedied through ordinary civil or criminal courts, not necessarily via Article 32.
• A constitutional right is one conferred directly by the Constitution but outside Part III — the right to property under Article 300A is the textbook example (post-44th Amendment), as is the right to vote under Article 326, or a Panchayat's constitutional status under Part IX. A constitutional right can only be taken away by a constitutional amendment (not ordinary legislation), but — unlike a Fundamental Right — its violation is not directly enforceable through the special writ jurisdiction of Article 32; a person must approach a court (often under Article 226, or through ordinary civil suit) for redress.
• A Fundamental Right, by contrast, sits in Part III, is directly enforceable via Article 32 (and Article 226), can be amended by Parliament only through the special Article 368 procedure and even then only subject to the Basic Structure doctrine (i.e., a Fundamental Right's amendment cannot destroy the Constitution's basic structure), and — per Article 13(2) — no ordinary law can override it at all.

The hierarchy, from weakest to strongest protection: legal right < constitutional right < fundamental right. The Right to Property's journey from Article 19(1)(f)/31 (a Fundamental Right) to Article 300A (a mere constitutional/legal right) after the 44th Amendment is the most-tested illustration of a right being deliberately demoted down this hierarchy.
