Based on the provided legal document, the key points are as follows:

1. The option for government servants to voluntarily retire with three months' notice after reaching 50 years of age or completing 25 years of service is not an absolute right. The decision to accept or reject such a request depends on the public interest and the discretion of the appointing authority (!) (!) (!) .

2. The relevant rules specify that retirement through voluntary notice requires an express order of approval from the appointing authority; it does not automatically come into effect upon expiry of the notice period unless explicitly accepted (!) (!) (!) .

3. The rules are statutory and bind both the government and the employee. They are not akin to a contractual agreement where automatic retirement occurs upon notice expiry; rather, the authority must actively approve the retirement (!) (!) (!) .

4. The language of the rules and their explanations clearly indicate that the decision to retire voluntarily is conditional and based on public interest considerations. The authority can refuse permission for retirement if it is deemed against the public interest, and such refusal must be communicated before the expiry of the notice period (!) (!) (!) .

5. The right to retire voluntarily is subject to the authority’s discretion, and the retirement does not become effective automatically without approval. The authority’s decision, whether to accept or refuse, is integral to the process (!) (!) (!) .

6. The rules provide that pension and retirement benefits are payable once the employee has retired in accordance with the rules, but the actual retirement is contingent upon the approval of the appointing authority (!) (!) (!) .

7. The legal interpretation emphasizes that the relationship of master and servant continues until the authority explicitly grants permission for retirement. The absence of communication of refusal within the notice period does not automatically mean retirement has occurred (!) (!) .

8. The rules prohibit withdrawal of a voluntary retirement request once made, except with the permission of the appointing authority, and any decision in this regard must be based on the conditions specified in the rules (!) (!) .

9. The rules also stipulate that in certain circumstances, such as pending disciplinary proceedings or suspension, permission to retire may be withheld, but such withholding must be communicated explicitly and within the notice period (!) .

10. Overall, the legal framework underscores that voluntary retirement under the rules is a process that requires active approval, and the rights of the employee to retire are not absolute but subject to the public interest and the discretion of the appointing authority (!) (!) (!) .
