I am sorry, but the provided information is insufficient to create a case summary. The case title "Article 89 in Constitution of India" is not a case title, but rather refers to a specific article within the Indian Constitution. There is no petitioner, respondent, or legal issue to analyze. Furthermore, the date provided is the date the Constitution came into effect, not a specific case date.

To provide a proper case summary, I need a valid case name (e.g., Kesavananda Bharati v. State of Kerala), the court that decided the case (e.g., Supreme Court of India), and a brief description of the facts and legal issues involved. With that information, I can create a summary following the requested format.
