Step 1: Understanding the Question:
The question asks for the true legal meaning and implications of the classic equitable maxim, "Once a mortgage, always a mortgage".
Step 2: Detailed Explanation:
• Origin of the Maxim: This maxim is a rule of equity formulated to protect mortgagors from being unfairly deprived of their property.
It emphasizes that the transaction, having started as a security for a debt (mortgage), must retain that character and cannot be converted into something else to block the right to recover the property.
• Clog on Redemption: Any provision in the mortgage deed or collateral agreement that prevents or restricts the mortgagor's right to redeem the property is called a "clog on redemption" and is held void by courts.
Therefore, the right of redemption is indefeasible and cannot be detached from the mortgagor. This supports statement (B).
• Redemption post Due Date: The mortgagor is entitled to redeem the mortgage at any time after the principal money has become due, provided the right has not been extinguished by act of parties or decree of a court. This supports statement (C).
Step 3: Final Answer:
Since both statements (b) and (c) correctly explain the implications of the maxim, the correct option is (D).
