Trinamool MP Mahua Moitra was expelled from Lok Sabha on Friday for "unethical conduct" in the cash-for-query case
She has the option of challenging the expulsion in the apex court, says former Lok Sabha Secretary General P D T Achary.
TMC leader can either challenge House's authority to expel her or claim she was denied natural justice
One major ground for a challenge is whether the House had the privilege to expel a Member.
The claim by Moitra that she was denied natural justice becomes a significant ground for challenge.
Achary highlights Article 20, stating a person can be punished only for a defined offence under existing law or rules.
The absence of a specific rule on sharing Parliament login-password raises a fundamental challenge.
Achary underscores the need for a rule or law to proceed against an individual for violating it.
