You mean they treated it as income. Am I right?
If yes then there is no contravention to sec 269T. 269T applies when repayment of loan is made otherwise than by an account payee cheque or bank draft or through electronic means of banking channels. Here in the present case, there is no repayment only. Instead what was a loan given is now treated as an income and not as due to the creditor anymore.
Kindly note that this loan income will be chargeable as income from other sources and not as business income. It means if you have shown it in p&l, then it is to reduced from your p&l to arrive at business income and would be separately disclosed in income from other sources.
