Dalam pelaksanaan jual beli saham, ada persyaratan Undang-Undang yang harus dipenuhi antara lain seperti diperolehnya persetujuan Rapat Umum Pemegang Saham Perseroan (RUPS) yang harus dimuat dalam akta notaris dan kemudian harus dibuatkan akta jual beli atas saham-saham tersebut. Tanpa dibuatnya akta jual beli tersebut, maka jual beli saham tersebut adalah batal demi hukum. Dalam putusan peninjauan kembali Mahkamah Agung mengenai kasus jual beli saham dalam PT.Bumi Mansyur Permai membatalkan putusan-putusan di ketiga tingkat peradilan karena terbukti terdapat kekhilafan dalam putusanputusan sebelumnya, dimana majelis hakim di ketiga tingkat keadilan menganggap dengan diadakannya RUPS, maka telah terjadi jual beli saham. Kasus ini dianalisis secara deskriptif analitis dengan menggunakan pendekatan yuridis normatif, dengan menitikberatkan pada sumber-sumber berupa peraturan perundang-undangan yakni antara lain peraturan mengenai pengalihan hak atas saham yang terdapat dalam Kitab Undang Undang Hukum Dagang, Undang Undang Nomor 1 Tahun 1995 dan Undang Undang Nomor 40 Tahun 2007 Tentang Perseroan Terbatas serta teori-teori hukum yang diperoleh dari tulisantulisan para ahli hukum. Sebagai hasil analisa penelitian ini dapat di tekankan pentingnya pembuatan akta jual beli saham sebagai persyaratan formal jual beli saham, setelah diperolehnya persetujuan jual beli saham dari RUPS yang sebenarnya hanya merupakan pemberian persetujuan kolektif atas penjualan saham.
