Theoretically possible for a chief minister to continue governing while under trial, certain legal provisions and practical considerations need to be addressed. In India, a chief minister is only disqualified upon conviction, not merely during trial. Therefore, if Arvind Kejriwal were in jail during the trial for a liquor scam, he could technically continue running the government unless and until convicted. However, several caveats apply:

1. Provisional Government Operation: The operational capacity of governing from jail may be limited due to logistical constraints and legal restrictions.
2. Administrative Challenges: Managing government affairs from jail could present administrative challenges, potentially affecting the efficiency and effectiveness of governance.
3. Public Perception: The public perception of a chief minister governing from jail could be detrimental to the credibility and integrity of the government.
4. Legal Oversight: There might be legal provisions or constitutional interpretations that could affect the ability of an incarcerated chief minister to perform official duties effectively.

Overall, while technically possible, the practicality and legality of governing from jail during trial raise significant concerns and would likely require careful legal scrutiny and consideration of various factors.
