The single judge will decide without undue delay, generally within 20 working days from the day it received a decision of another Member State along with a certificate, whether the decision of the other Member State will be recognized, and executed or it will not be recognized. In case an appeal has been filed against the decision of the other Member State, the time limit set in the first sentence shall be extended with another 20 working days. The time taken for translating the decision or certificate or acquiring documents from the other Member State necessary for making the decision will not be counted into time limit referred to in the sentences one and two. If this time limit cannot be kept, the single judge shall immediately notify the competent authority of the other Member State thereof and state reasons for the delay, including the expected duration of such delay.
