S. 10A: Free trade zone – Mere higher profit margin vis-à-vis comparable companies or sister concerns, without any material establishing an arrangement to inflate profits between the assessee and its associated enterprise, does not justify invocation of s. 10A(7) r.w.s. 80-IA(10) for restricting deduction- The provisions can be invoked only where there is evidence of an arrangement resulting in more than ordinary profits.
