"The (Supreme) Court's recent experiment with constituting an exclusive bench for taxation produced impressive results, which may be replicated for other subject matters, and emulated by other High Courts that do not have special rosters for daily hearings," said the 2017-18 Survey.
Authored by a team led by Chief Economic Advisor Arvind Subramanian, the Survey said since the constitution of the tax bench in 2014, the Supreme Court has been able to reverse the trend of burgeoning pendency of tax cases.
Stating that there are other "profound benefits" of dedicated subject-matter benches, it said such benches ensure that the Supreme Court speaks in one voice, and there is continuity and consistency of legal jurisprudence.
"Further, they create efficiencies by allowing the judge to focus on the specialised branch of law placed before her. The model may be replicated for other commercial and economic areas of law as and when necessary at the Supreme Court, and should be replicated by every High Court of the country," the Survey said.
