Writ jurisdiction and legal metrology rules: contractual supply terms could not be altered, and litre-based petroleum supply was permissible.

Writ jurisdiction was found unsuitable for disputes that would alter contractual supply terms between dealers and oil companies, particularly where contractual and statutory remedies were available and the agreements were not produced. The challenge to sale and supply of petroleum products in litres also failed because the Legal Metrology framework recognises litre as a permitted unit of volume, including for liquid measurement under the relevant rules and schedules. On both maintainability and merits, the writ petitions were dismissed and the appeals failed.

Issues: (i) Whether the writ petitions were maintainable in view of the contractual dispute resolution mechanism between the dealers and the oil companies. (ii) Whether sale and supply of petroleum products in litres was contrary to the Legal Metrology Act, 2009 and the rules framed thereunder.

Issue (i): Whether the writ petitions were maintainable in view of the contractual dispute resolution mechanism between the dealers and the oil companies.

Analysis: The reliefs sought would necessarily affect the contractual terms governing supply of petroleum products. The agreements were not produced, and the appellants did not show that the directions sought could be granted without altering the bargain between the parties. In such circumstances, disputes arising from the contract could not be enforced through writ jurisdiction when the contractual and statutory remedies were available.

Conclusion: The writ petitions were not maintainable and the appellants could not invoke writ jurisdiction to seek modification of contractual supply terms.

Issue (ii): Whether sale and supply of petroleum products in litres was contrary to the Legal Metrology Act, 2009 and the rules framed thereunder.

Analysis: The statutory framework permits measurement of volume in litres. The Legal Metrology Act, 2009 and the Legal Metrology (National Standards) Rules, 2011 recognise the International System of Units and permitted units, including litre as a unit of volume. The Legal Metrology (General) Rules, 2011 and the Legal Metrology (Packaged Commodities) Rules, 2011 also contemplate measurement of liquids by volume, and the prescribed schedules include measurement by dip-rod method in litres. The appellants therefore failed to establish that supply in litres violated the metrology regime.

Conclusion: The challenge based on the Legal Metrology law failed, and litre-based supply was held to be permissible.

Final Conclusion: The appeals failed both on maintainability and on merits, and the dismissal of the writ petitions was sustained.

Ratio Decidendi: A writ court will not grant relief that effectively alters contractual terms governing a commercial arrangement, and litre is a legally permitted unit of volume under the Legal Metrology framework.
