C. and Section 3 (1) (xi) of the Scheduled Castes and the scheduled Tribes (Prevention of Atrocities) act, 1989 (for short the SC and ST (POA) act ).

W. 3 had gone to the outskirts of duggapur Village for the purpose of grazing the goats and at about 11-00 am, the accused suddenly came there, caught hold of the hand of P. W. 2 and dragged her towards nearby bushes. Then, P. W. 2 raised cries and on hearing the cries, P. W. 3 rushed to the spot. The accused threatened P. Ws. 2 and 3 by showing the axe at them. The villagers reached the spot and rescued P. W. 2 and the accused was brought to the Police Station, tiryani and on report of P. W. 1, a case in crime No. 10 of 1996 was registered and investigated and the accused was arrested on 27-4-1996.

C. and the main sentence of imprisonment was directed to run concurrently. Aggrieved by the same, the present appeal is preferred. ( 4 ) IT is not in controversy that the date of offence is 27-4-1996. The Scheduled castes and the Scheduled Tribes (Prevention of Atrocities) Rules, 1995 came into force from 1-4-1995. P. W. 5, Assistant Sub-Inspector, had investigated into the offences with which the accused had been charged with and recorded the statements of witnesses. It is no doubt true that Rule 7 has no retrospective operation. Investigation prior there to in relation to offences under the SC and ST (POA) Act also was being conducted by regular Investigating Agency but, however, specific rule i. e. , Rule 7 was introduced by which the specified officer has to conduct investigation. This check was introduced by putting a specific bar in conduct of investigation by other investigating Officers other than the specified in the rule with a fond hope that such offences to be investigated with better care and caution, more concerned with social compulsions, order and disorder and hence, if investigation is entrusted to a higher officer, the same may be proceeded with on sound lines. Be that as it may, apart from this aspect of the matter, cognizance was taken by the learned Special Judge straightaway and hence due to non-committal of the case in view of clear language of section 193 Cr. PC, the whole trial is vitiated. Viewed from any angle, the conviction and the sentence imposed as against the appellant accused cannot be sustained and accordingly, they are hereby set aside. . ( 5 ) THE criminal appeal is allowed.
