Answer:
only irregular, which can be confirmed by shareholders and ratified.
Step-by-step explanation:
An Article can be defined as rules, regulations and bye-laws that are binding on a corporation and generally used for internal management.
Corporation is considered to be one of the most complicated and expensive type of organization. Thus, it is considered to be a body that comprises of a group of people such as directors, shareholders etc. who act as a single entity and it's perpetual in nature. It can be sold through stocks or shares, as a public eentity.
If a company does something in contravention of the Articles, it is only irregular, which can be confirmed by shareholders and ratified.
This ultimately implies that, when a company's Act (Articles) is contravened, it is just an irregularity and as such can always be confirmed by the shareholders and ratified or rectified accordingly.
