Disobeying the G.O. on permissibility of HRA to working couples

My spouse used to draw HRA @15% of her basic pay i.e.3525/- and I used to draw 2475/- as per ROPA,2009. After my posting at Jalpaiguri from Bolpur,our permanent residence , I applied before my Department(Agriculture) to allow me full HRA due to distance of working place of more than 450 Kms. Vide memorandum No.955-SE(Law)/SL/5S-1221/09 dt.27.07.2011. Dy. Secy. Agriculture Department allowed me to draw full HRA i e. Rs.6000/- vide No.2752-Estab(Dte)/AG/O/OP-04/2018 dt.6.3.2019 with the concurrence of Fin. Department vide UO No. Group P2/2018-19/0899 dt.16.1.2019. I am drawing full HRA of Rs. 6000/- subject to my spouse HRA of Rs 3525/- in relationship details of Ifms module and is duly accepted by the system. But Education Deptt to which my spouse is an employee has rendered her HRA to 0 or nil? Are she not entitled to full HRA by virtue of my approval order? Is there any need to get separate approval from her Deptt. Within the same Govt? Kindly assist me with clear reply.
