Decree Holder - Cannot delete some of dependents
The provided source (R.B.I. vs PEERLESS GENL. FIN. & INVEST.CO. - Supreme Court) discusses insurance subscription amounts, deductions, and the role of the Life Insurance Corporation, but does not directly address the issue of a decree holder's authority to delete dependents. However, in insurance law, the decree holder's rights are typically limited to the benefits and claims as per the policy terms, and they generally cannot unilaterally alter or delete dependents listed in the policy without proper legal authority or the policyholder's consent.

Analysis and Conclusion
Based on standard legal principles and the context of insurance policies, a decree holder does not have the authority to delete or alter dependents listed in the policy unless explicitly permitted by the policy terms or through a court order. The insurer's role is to honor the policy as issued, and any modifications to dependents usually require the policyholder's consent or legal intervention. Therefore, the decree holder cannot delete dependents unilaterally.
