The Aam Aadmi Party is preparing legal action after seven of its Rajya Sabha members formally merged with the Bharatiya Janata Party (BJP).

This shift significantly alters the balance of power in the upper house of India's parliament. The merger reduces the Aam Aadmi Party's (AAP) influence while expanding the ruling party's legislative footprint during a critical period of governance.

The Rajya Sabha Chairman approved the merger on April 28, 2026 [1]. Following this decision, the BJP's strength in the Rajya Sabha rose to 113 seats [1]. Conversely, the number of AAP members in the chamber fell from 10 to three [1].

AAP leaders said they are currently completing procedural formalities before deciding on further legal steps. The party has sent a third letter to the Rajya Sabha Chairman after receiving no response to two previous communications [2]. Sanjay Singh, an AAP leader, said, "We will take legal action if the merger is not reversed" [3].

The merger has drawn sharp criticism from political opponents. Partap Singh Bajwa said, "The nexus between the Bharatiya Janata Party and the Aam Aadmi Party has been exposed" [3]. Other critics have been more severe; Congress leader Harbhajan Singh said that AAP has sold its Rajya Sabha seats [3].

While the BJP views the merger as a legitimate increase in its parliamentary strength, other political figures describe it as a calculated attempt to manipulate the house [4]. This disagreement underscores the tension between party loyalty and the legal mechanisms governing legislative mergers in New Delhi.

"We will take legal action if the merger is not reversed."

The sudden migration of seven MPs from AAP to the BJP represents a significant blow to AAP's legislative standing and suggests a strategic consolidation of power by the BJP. If the courts do not intervene to reverse the merger, the BJP will have a stronger mandate to push through legislation in the Rajya Sabha, while AAP faces a crisis of internal stability and public perception regarding its party discipline.
