In this situation the NRP had previously offered to miss a contact session to allow for holiday time. The RP disregarded this suggestion and booked a holiday over a different contact session that had not been agreed by both parties.
The order states that the RP can not breach the order 'without good reason'.
Its also worth mentioning that the RP repeatedly refuses to allow the NRP to take the child on holiday.
Would giving the child a holiday be a 'good reason'? Given that the NRP had offered to miss time to allow for holiday time and has also been denied the opportunity to give the child a holiday themselves.
