Secundrabad Club Etc. vs C.I.T.-V Etc.
Background
This common judgment disposed of appeals by several members' clubs: Secunderabad Club (from the Andhra Pradesh High Court) and Madras Gymkhana Club, Madras Cricket Club, Coimbatore Cosmopolitan Club, Madras Club, Wellington Gymkhana Club and the Coonoor Club (from the Madras High Court). Each club had deposited its surplus funds in banks and earned interest on them, and argued that this interest should not be taxed because of the "doctrine of mutuality": the principle that money circulating only among a club and its own members (like membership fees) isn't taxable income, since a person cannot "profit" from themselves. The High Courts in each case had ruled that this interest was taxable and that mutuality did not apply.
Decision Breakdown
The Supreme Court reviewed a trilogy of its own earlier rulings (Bankipur Club, Cawnpore Club and Bangalore Club) and held that the 1998 Cawnpore Club order was not a binding legal precedent because it never actually decided the mutuality question for bank interest. It then held that its 2013 decision in Bangalore Club vs. CIT (which held such interest taxable, because a bank remains a separate commercial entity dealing with the club at arm's length even if the bank happens to also be a corporate member of the club) did not need reconsideration and was not decided "per incuriam" (in ignorance of binding law). Consequently, interest earned by a club on its bank deposits is ordinary taxable income under the Income Tax Act, regardless of whether the depositor-bank is itself a member of the club, and all the connected appeals were dismissed.
Lesson Learnt
The tax-free "mutuality" principle that protects transactions purely between a club and its own members does not extend to interest earned by parking the club's surplus funds in a bank; a bank is treated as an outside commercial party for tax purposes, so that interest remains taxable income.
