Assignment versus subrogation: operative terms controlled the instrument, and the insurer's suit was held maintainable.

A document labelled as a letter of subrogation was construed by its operative terms, not its title, because it expressly assigned, transferred and abandoned the insured's rights against the wrongdoer in favour of the insurer and authorised recovery in the insurer's own name. On that construction, the instrument was held to operate as an assignment rather than a mere subrogation letter. The insurer's suit was therefore maintainable, and the challenge based on nomenclature was rejected. The appeal failed and the decree in favour of the insurer was sustained.

Issues: Whether the document styled as a letter of subrogation was in substance a deed of assignment, and whether the suit filed by the insurer was maintainable.

Analysis: The document, though labelled as a letter of subrogation, expressly stated that the insured assigned, transferred and abandoned all rights against the wrongdoer to the insurer and authorised the insurer to recover the loss in its own name. The governing principle is that a document must be construed according to its contents and legal effect, not by its nomenclature. On that construction, the instrument operated as an assignment in favour of the insurer.

Conclusion: The suit was maintainable and the contention that the document was only a subrogation letter was rejected.

Final Conclusion: The appeal failed and the decree in favour of the insurer was sustained.

Ratio Decidendi: A document must be interpreted by its operative terms and legal effect, and where it transfers and assigns rights in favour of the insurer, it is to be treated as an assignment notwithstanding its label as subrogation.
