Engagement of experts or professionals now requires fixed contractual tenure and updated qualification and experience criteria. Amendments expand the defined category to 'experts or professionals including research associates' and substitute regulation 8(1) to provide that such experts or professionals including research associates shall ordinarily be engaged by the Commission on contractual basis for not less than one year and not more than three years. The amendments further revise Schedule I to set essential and desirable qualifications and experience for legal posts, and amend Schedule II to change preferred experience for Level I to one to three years.
