But in the case of " R.B.N.J Naidu Vs CIT (1956) 29 ITR 194 (Nag) and R.Dalmia Vs. CIT (1982) 133 ITR 169 (Delhi) " , it says income from investment out of pin money cannot be clubbed.
Pin money received by wife from her husband is not treated as an income in the hands of wife & so if she saves from Pin money & invests the same, the income from Investment will be taxed in the hands of wife & no clubbing provisions will apply here.
The concept of pin money is that of a personal allowance hence any investment done for it would be the income of the wife only.
However the assessing officer may take judgement regarding the amount of such investment and classify it accordingly.
