Key legal question
Whether the Federal Supreme Court should change its case law and distribute the maintenance deficit between spouses and children.
Extracted holding
No. The existing rule leaving the obligor's subsistence minimum untouched and allocating the deficit to the maintenance creditors remains in force.
Extracted reasoning
Although the material family-law provisions and equality considerations could support deficit sharing, practical problems in coordination with social assistance and enforcement, together with the need for legal certainty, outweigh the arguments for a doctrinal change.
