Examine the tension between judicial mandates and regulatory autonomy, taking the example of IRDAI's third-party motor insurance guidelines.

Regulatory autonomy assumes a statutory body like IRDAI will fix technical insurance norms within its domain; a judicial mandate directs those norms in public interest. The Supreme Court's successive orders on long-term third-party (TP) motor cover expose this friction sharply.

Why the judiciary entered the field

• Section 146, Motor Vehicles Act, 1988 makes TP cover compulsory, yet a large proportion of vehicles ply uninsured, leaving accident victims to pursue owners with no capacity to pay [1][4].
• In S. Rajaseekaran v. Union of India (2018) the Court used continuing mandamus under Article 32 to mandate long-term TP cover at purchase — 3 years for new cars, 5 years for two-wheelers — implemented by IRDAI from 1 September 2018 [2].
• In August 2026 the Court raised tenures to 4 and 6 years, and ordered ANPR cameras to be integrated with IIB insurance data and VAHAN registration records to auto-detect uninsured vehicles [3].

Where the tension lies

• Regulator overruled: IRDAI and the General Insurance Council had recommended against the enhancement; the Court still ordered it, leaving IRDAI as an implementing agency rather than a decision-maker [3].
• Technical domain displaced: tenure and pricing of TP cover are actuarial judgments — IRDAI itself withdrew long-term package covers in 2020 on affordability grounds, showing regulatory reasoning can legitimately diverge from court-set product design [2].
• Separation of powers: policy instrument choice is executive-regulatory; courts risk substituting judicial preference for expert consultation.
• Counterweight: persistent non-compliance and victims' Article 21 interest in timely compensation justify corrective judicial pressure where regulation under-delivers [4].

The friction is less a clash of institutions than a symptom of a compliance deficit that regulation alone did not close. The durable balance is for courts to set outcome standards — measurably fewer uninsured vehicles — while leaving instrument design to IRDAI, backed by technology-led enforcement through ANPR–VAHAN–IIB linkage and structured regulator–ministry consultation. Regulatory autonomy is best protected by regulatory performance.
