Bylaws
In one sentenceThe document that governs a joint stock company and sets out its name, objects, capital, shares, and the powers of the board of directors and general assemblies.
Simply put
It corresponds to the memorandum of association in other companies, but is more detailed on governance: the composition and term of the board, how the general assembly is called, the quorum for its meetings, and share classes.
Amending it usually requires a resolution of the extraordinary general assembly, and the amendment is registered with the Ministry of Commerce.
Example
A simplified joint stock company wanted to issue a new class of shares to an investor. The adviser reviewed the bylaws to see whether this was allowed, then they were amended by a shareholders' resolution and the amendment was registered.
Don't confuse it with
Memorandum of associationThe memorandum of association is the document of limited liability companies and partnerships, while the bylaws are the document of a joint stock company.
