There in lies the rub. It says his "plans for a memorial service". If he's not had one?
My read, which is indirect because it is only news reports, is that he can obey the court order and avoid communicating with the Schindlers by having no plan. He is required to report his plans (and I assume also that the court order expects his actions in the burial and services will comport with his plans). As long as he plans nothing, and just leaves her remains "wherever," he has not violated the court order.
