# Role of Audit Committee in Auditor Appointment
Where a company is required to have an Audit Committee (AC) under Section 177, certain auditor-related matters must pass through the AC.
## Matters requiring AC's recommendation
For companies required to constitute an Audit Committee, the Board shall consider the recommendation of the Audit Committee in respect of:
1. Appointment of auditor
2. Re-appointment of auditor
3. Filling of casual vacancy in the office of the auditor
## Voluntary vs Mandatory AC — key distinction
| Audit Committee Type | Effect |
|---|---|
| Mandatorily constituted (Section 177 requirement) | Board must consider AC's recommendation |
| Voluntarily constituted (where no statutory requirement) | Board may or may not consider its recommendation |
## Important nuances
- The AC's recommendation is not binding on the Board; the Board only needs to consider it.
- If the Board disagrees with the AC's recommendation, the Board records reasons and proceeds; the matter then goes to shareholders.
- For companies that are not required to constitute an AC but have done so voluntarily, this consideration requirement does NOT have statutory force.
## Quick recall
- AC → recommends
- Board → considers (mandatory consideration only if AC is mandatorily constituted)
- Shareholders → appoint at GM
