What is unprecedented about the Chief Minister's oath-taking ceremony in Delhi?

This marks the first time invitation cards are being distributed for a Chief Minister's oath-taking ceremony while the identity of who will take the oath remains unknown. The unique situation has created significant suspense as the BJP has not revealed their choice for the new Chief Minister, despite preparations advancing to the point of distributing formal invitations. This unprecedented approach has drawn criticism from opponents who suggest it undermines traditional political protocols. Only the BJP leadership knows the reasoning behind this unusual strategy, which has been characterized as potentially damaging to established governmental traditions and dignity in the political process.
