Key legal question
Whether the constitutional complaint remained admissible despite the alleged move of the child to B.
Extracted holding
The complaint remained admissible because the move was unclear, the school assignment depended on actual residence rather than paper registration, and the issue could recur.
Extracted reasoning
The court held that the new registration in B. did not clearly extinguish the legal interest. It may have been connected to the dispute, and the legal question could arise again.
