Source and Evolution of the doctrine
Article 159 of the current (2010) form of the Federal Constitution of Malaysia reflects the basic structure doctrine.
The case of Loh Kooi Choon v Govt. of Malaysia  2 MLJ 187 involved a constitutional amendment that deprived Loh, the appellant, of protection from detainment without magistrate authority. Loh cited the Kesavananda case in arguing that the amendment destroyed the basic structure of the amendment. The court rejected Loh's argument, holding that the constitution could not be internally inconsistent. In Phang Chin Hock v Public Prosecutor  1 MLJ 70, the court again rejected the basic structure argument, holding that "Parliament may amend the Constitution in any way they think fit, provided they comply with all the conditions precedent and subsequent regarding manner and form prescribed by the Constitution itself".
The doctrine was first cited with approval by the Federal Court in obiter of the Sivarasa Rasiah case  2 MLJ 333. The court held, "Further, it is clear from the way in which the Federal Constitution is constructed there are certain features that constitute its basic fabric. Unless sanctioned by the Constitution itself, any statute (including one amending the Constitution) that offends the basic structure may be struck down as unconstitutional." The doctrine was later enshrined as part of the constitution in Article 159, having been amended as of 2010. It has been upheld in later judgments, such as Semenyih Jaya Sdn Bhd vs Pentadbir Tanah Daerah Hulu Langat & Another  1 LNS 496.
