Penelitian ini meninjau mengenai penerapan Article V(1)(b) Konvensi New York 1958 dalam permohonan pelaksanaan putusan arbitrase asing pada pengadilan Amerika Serikat dan Inggris, dengan menggunakan metode yuridis normatif melalui studi kepustakaan. Berdasarkan hasil penelitian, dapat diketahui bahwa Amerika Serikat dan Inggris merupakan negara anggota peserta Konvensi New York 1958 yang telah menerapkan reciprocity reservation berdasarkan Article I(3) konvensi tersebut. Penerapan Article V(1)(b) di kedua negara tersebut tunduk pada standar hukum nasional masing-masing mengenai due process. Sebagaimana dapat dilihat dalam kasus CEEG (Shanghai) Solar Science & Technology Co. Ltd. V. Lumos LLC, Tianjin Port Free Trade Zone Int'l Trade Serv. Co. v. Tiancheng Chempharm, Inc. U.S. dan Zavod Ekran Oao v. Magneco Metrel UK Ltd, pengadilan menerapkan standar yang berbeda dan memiliki pertimbangan yang berbeda dalam menentukan apakah telah terjadi pelanggaran terhadap Article V(1)(b) Konvensi New York 1958.
