1. You may file a Review Application before the 10th ADJ alongside an Application for Stay of Operation of the order and can ar4gue based on the Supreme Court judgment in Rajnesh v. Neha (2021), which states that arrears should not be granted mechanically from the date of application if it causes oppressive financial burden, and the court must adjust/deduct payments made in-kind or direct educational expenses.
2. You are right that per incuriam applies to binding judicial precedents/statutes ignored by a co-coordinate or higher court, but in a trial/district court, non-compliance with mandatory High Court circulars/guidelines amounts to a jurisdictional error and ground for Review. Therefore an order passed in ignorance of binding judicial directions issued by the jurisdictional High Court (WPA (P) 166 of 2022 under Article 226/227) may be deemed as an "error apparent on the face of the record.
3. You can carefully plead the concept of jurisdictional overlap because under Section 38 of the Special Marriage Act (SMA) governs custody, maintenance, and education of children during matrimonial proceedings. If the 12th ADJ is already adjudicating custody under Section 25/12 of the Guardians & Wards Act (GWA) along with an active Parenting Plan, parallel fixing of unadjusted cash maintenance without reference to the custody schedule causes conflicting determinations.
4. You can pray for consolidation/transfer of the matrimonial suit/maintenance aspect to the court handling the GWA case to prevent contradicting orders and argue that multiplicity of proceedings on identical issues (child support vs. custody sharing) is contrary to public policy.
5. You can argue that ignoring mandatory procedural requirements (such as the HC Child Access & Custody Guidelines 2025 filing requirements) violates procedural natural justice.
6. You can argue that fragmented adjudication leads to unjust enrichment of one parent and starves the actual child welfare infrastructure. Child support cannot be treated merely as a monetary payment to the mother when the father provides direct physical care for 15 days, pays school fees, and provides health insurance.
7. If the order was passed strictly under an application named "Section 36 SMA" and awarded child maintenance without invocation/recourse to Section 38 SMA or Section 26 HMA principles, it suffers from a structural defect.
8. You may file a Review petition and an application for Stay (Order 47 Rule 1 and Sec 151 CPC) and highlight Non-consideration of standard direct expense, Misapplication of Section 36 SMA (which is for wife only) for child maintenance without following Section 38 SMA guidelines, 50% shared physical custody arrangement. If the Trial Court refuses a stay or rejects the review, file a Revision (C.O.) before the High Court, invoking non-compliance with WPA (P) 166 of 2022 guidelines.
