Final answer:
Under Listing Rule 3.1, the board of directors is not required to approve all announcements made by a company. This conclusion is supported by the cases ASIC v Mack Donald (No11) [2009] NSWSC 287 and Morley v ASIC [2010] NSWCA 331.
Step-by-step explanation:
Under Listing Rule 3.1, it is not a requirement for the board of directors to approve all announcements made by a company. This is highlighted in two cases: ASIC v Mack Donald (No11) [2009] NSWSC 287 and Morley v ASIC [2010] NSWCA 331.
In ASIC v Mack Donald the court held that the board of directors should exercise reasonable care and diligence in the discharge of their duties, but it did not explicitly state that board approval was required for all announcements. Similarly, in Morley v ASIC, the court emphasized that the responsibility of ensuring compliance with the Listing Rules lies with the company as a whole, not just the board of directors.
Therefore, based on these cases, it can be concluded that there is no requirement for the board of directors to approve all announcements made under Listing Rule 3.1.
