If Rule 165 A of the Bombay Civil Services (Classification, Control and Appeal) Rules, as amended, which fell to be considered in Saubh Chand Doshi 's case (1) was not invalid, if Rule of the Railway Services (Safeguarding of National Security) Rules, 1949, which fell to be considered in P. Balakottaiah 's case(2) was not invalid, if Rule 278 of the Patiala State Regulations which fell to be considered in Dalip Singli 's case (3) was not invalid, if Rule 5(a) of the Central Government Services (Temporary Service) Rules, 1949, which fell to be considered in Satish Chandra Anand 's case (4) was also not invalid, it is difficult to appreciate any ground either of logic or of law on which the vice of invalidity as infringing article 311(2) may be attributed to Rule 148(3).
