B.Arch admission through TNEA 2022

This is regarding B.Arch Admission conducted by TNEA 2022 (Tamil Nadu Engineering Admission), NATA (National Aptitude Test in Architecture) entrance was Initial criteria for securing admission later JEE (after commencement of JEE) also included as eligible for admission. Today the rank list was published where they have worked out rank based on both NATA and JEE marks. There is a drastic change in the rank due to the inclusion of JEE marks. 1. Initial Notification published by NATA on 12.3.2022 does not mention about the JEE. 2. After the commencement of JEE exam, on 20.7.2022 NATA published notification stating JEE could be considered as eligibility criteria for B.Arch admission. 3. On 05/10/2022 TNEA published the rank list where they have worked out the rank list based on both NATA and JEE Marks. There was no proper intimation to the candidate regarding dual system of evaluation before the commencement of both entrance exams, I would like to take this issue legally. Kindly let me know your opinion.
