Dear CA Darryl Martis
I am not aware of the case laws, but if your query is related to current or future transactions i believe there is no need to refer to any case laws since the new rule Rule 37 BA (read with section 199) has come into effect. Below is the Rule which is self explanatory. Even i am in the same situation where i have invested in FDs in my wife's name and am going to submit declarations to banks under rule 37BA.
[Credit for tax deducted at source for the purposes of section 199.
