The deal over the islands of Tiran and Sanafir prompted some of the largest public protests in two years when it was signed in April.
The country’s State Council ruled on Tuesday that the islands, strategically situated at the mouth of the Gulf of Aqaba, must remain under Egyptian sovereignty.
“The government will present all the documents it has to demonstrate the integrity and strength of the case it presented to the Supreme Administrative Court which has the right to rule on the case,” the prime minister’s office said in a statement on Wednesday.
“It will also present a dossier containing documents and maps that will assist in resolving the case.”
