The appeals are being decided by a common judgment because identical issues arise for consideration in all the appeals, the common appellants whereof are the Army Welfare Education Society and either Army Public School, Dhaula Kuan or the Army Public School Delhi Cantonment. Both schools are independently recognized under the Delhi School Education Act, 1973 and the rules framed thereunder and are thus separate juristic entities, but having a common linkage because of the fact that the society which established the schools is the same i.e. Army Welfare Education Society. Manju Nautiyal was appointed as a Primary Teacher, Shayam Dutt as an Estate Supervisor, Anita Soharu Guleria as TGT Science (Biology), Renu Barrot as TGT Computer Science, Ravi Kumar as Computer Lab Helper, Vikram Singh and Shatrughan Thakur as Drivers, Sheeja Benoy as Nursing Assistant and Bir Singh as LDC (Account Clerks).
