that a person holding a Diploma is eligible to be promoted to the post covered by Bihar Engineering Services Class I Rules, 1939. Here it is relevant to mention that initially the Engineering Service Rules were framed in 1930s and the stipulated qualification was only a degree in engineering. Thereafter it was noticed that Thomason College, Roorkee, which has since become I.I.T., Roorkee, was issuing Diploma to students who studied 4 years course of Civil Engineering, and having regard to the quality of education in that institution, it is essential that the rules must be amended to include the word “Diploma” in its restricted sense in Rule 8 of the qualifications. Accordingly, the Rule was amended in 1939. This was slightly amended in the year 1969 and thereafter in the year 1971 to the effect that the holder of any Diploma awarded by any institute whatever shall be eligible for promotion to Class I. The Rules were amended in the year 2006 restoring the Rule 8 as it stood in the year 1939.
