I have found out that there are several more legislations which are in pari materia (read as similar in nature) to S15 UUCA.
S15 UUCA is a clause on the "prohibition to join society, political party, trade union and other organisation except approval obtained in advanced".
1. Section 15: Universities and Universities College Act -- applicable to all public universities/universities colleges with the exception of UiTM and IIUM.
2. Section 47: Private Higher Educational Institutions Act 1996 -- applicable to private institutions.
3. Section 23F: University Technology Mara Act 1976 -- applicable to UiTM only.
4. Section 10: Educational Institutions (Discipline) Act 1976 -- applicable to all teachers training colleges, Institut Technologi Mara and Polytechnics.
5. Rule 28 Students' Discipline Rules 2004 of International Islamic University (IIU)
