Economic offences - anticipatory bail under Section 438 CrPC - custodial interrogation - public interest in investigation of economic offences - non-cooperation with investigation - seriousness of allegations involving large-scale duty evasionAnticipatory bail under Section 438 CrPC - economic offences - custodial interrogation - non-cooperation with investigation - Application for anticipatory bail of the applicant/accused - HELD THAT: - The court considered the nature and gravity of allegations of large-scale duty evasion, the applicant's admitted involvement in manufacture without valid registration, the department's contention of non-cooperation and evasive replies during investigation, and authorities holding that economic offences constitute a separate class requiring a cautious approach to bail. The court accepted that custodial interrogation may be necessary to elicit concealed information and to advance investigation into the extent of alleged evasion, and observed that pre-arrest protection may impede effective interrogation in such cases. Having regard to these factors and the desirability of disinterring unraveled aspects of the offence, the court concluded that this was not a fit case for exercise of discretion in favour of anticipatory bail.Anticipatory bail application rejected.Public interest in investigation of economic offences - seriousness of allegations involving large-scale duty evasion - Conduct of the complainant Department during investigation and appropriate administrative action - HELD THAT: - The court noted a prolonged period of inactivity by the department between November 2017 and July 2019 despite serious allegations, observed that evidence in tax-related criminal matters is ephemeral and requires diligent, time bound inquiry, and expressed concern at apparent lethargy. In view of these observations, the court called for personal attention by the Principal DG, DGGI and requested initiation of appropriate remedial action against erring officials.Principal DG, DGGI to look into the matter personally and consider remedial action; copy of order to be sent to Principal DG, DGGI.Final Conclusion: Anticipatory bail denied; court directs administrative review of departmental conduct by Principal DG, DGGI and disposal of the application accordingly.
