Supreme Court heard ED plea seeking CBI investigation into alleged obstruction of I-PAC search involving Mamata Banerjee

The Supreme Court on Tuesday continued hearing the Enforcement Directorate’s plea seeking a CBI investigation into the alleged obstruction of an ED search at the office of Indian Political Action Committee (I-PAC), a political consultant associated with the Trinamool Congress, involving former West Bengal Chief Minister Mamata Banerjee and certain State police officers.

The Bench of Justices P.K. Mishra and N.V. Anjaria heard extensive submissions on the maintainability of the ED’s plea under Article 32 and whether the matter should be transferred to the CBI.

Solicitor General Tushar Mehta, appearing for the ED, maintained that the agency was pressing its plea and urged the Court to decide the issue rather than leave it to the present West Bengal government following the change in government.

“We are pressing our petition. We want Your Lordships to decide whether we are right or wrong,” Mehta submitted.

He said the ED did not want a subsequent decision by the State government to transfer the case to the CBI to invite allegations that the transfer was politically motivated merely because there had been a change in government.

“We don’t want to fall into that trap,” Mehta said, adding that the Court could either dismiss or allow the petition, but should decide the issue itself.

Earlier, Senior Advocate Menaka Guruswamy, appearing for the respondents, submitted that with the change in government in West Bengal, the present government could decide whether the matter should be investigated by the State police or transferred to the CBI.

The Bench questioned why the Court should decide the issue if the State was now willing to consider the appropriate course of investigation.

Guruswamy, however, objected to the Court itself directing a transfer and maintained that the respondents were not conceding anything.

Additional Solicitor General (ASG) S.V. Raju raised a broader question: whether an alleged offence committed by a sitting Chief Minister should be investigated by the State police or transferred to the CBI.

Guruswamy responded that this was not the basis on which the matter should be decided.

During the exchange, Mehta told Raju: “Maintain your dignity, Mr Raju. At least you are a senior law officer.”

Raju later submitted that the issue had to be examined with reference to the circumstances prevailing at the time of the alleged offence and not merely because there had subsequently been a change in government.

Raju told the Court that he had completed his submissions and relied on several judgments, including State of West Bengal v. Committee for Protection of Democratic Rights, to contend that the Supreme Court had the power to direct a CBI investigation.

He also relied on Section 156 CrPC, submitting that the ED could not obtain the relief it sought by approaching a Magistrate, as the Magistrate did not have the power to direct investigation in the manner sought.

Raju said he had also addressed the maintainability of the petition under Article 32.

He submitted that offences including theft were also made out and said a list of alleged offences had been placed before the Court. Raju further relied on A.K. Antulay to contend that any person could set the criminal law in motion.

He also addressed the ED’s plea concerning cross-FIRs and pointed to the prayer seeking a writ of mandamus directing registration of an FIR over the alleged obstruction of public officials.

Guruswamy, appearing for former Chief Minister Mamata Banerjee and other respondents, objected to the matter proceeding to merits. She submitted that she, Senior Advocates Kapil Sibal and Shyam Divan, had so far argued only on maintainability and had not been heard on merits.

“We will file written submissions,” she said.

Justice P.K. Mishra, however, observed: “There won’t be piecemeal hearing.”

The Bench said the questions of maintainability and merits were intertwined.

“There is nothing on merits. If you argue on merits, whatever it is, then there will be difficulty for you,” the Bench told Guruswamy.

Guruswamy responded: “Then rule on merits.”

Justice Mishra observed that if the Court found the plea maintainable, it could refer the matter to the CBI. However, if the parties wanted the Court to decide the merits, “we will say something you should be ready for.”

“Please begin,” the Bench said, asking Guruswamy to address the merits.

Guruswamy thereafter began her submissions by stating that her first argument would be on maintainability.

Justice Mishra said, “We will go by the watch.”

Guruswamy replied: “My Lords will go by the Constitution, I know.”

Justice Mishra responded: “We will regulate our Court.”

Guruswamy submitted that the protection available to every citizen under Part III of the Constitution would be diluted if the Court did not first determine the maintainability issue. She said the respondents had proceeded on the understanding that the Bench would decide maintainability first.

“Be that as it may, I have five judgments to submit that a writ petition seeking registration of an FIR is not maintainable,” she submitted.

She began with Sakiri Basu v. State of Uttar Pradesh, asking the Bench to consider the judgment.

Raju countered that Sakiri Basu itself dealt with maintainability. He argued that the Magistrate could not direct a CBI investigation, which was why the ED had approached the High Court under Article 226.

Guruswamy responded that the ED had filed a writ petition and said the matter raised the question of whether registration of an FIR could be directed through a writ petition.

She subsequently relied on the Kantilal Patel judgment. Raju responded that he did not want the West Bengal Police to investigate and argued that the judgments relied upon by Guruswamy concerned cases where investigation by the local police was sought.

Guruswamy also informed the Court that the respondents would place on record a note citing 12 judgments which, according to her, consistently held that matters involving adjudication of disputed facts should not be decided under Article 32.

At the conclusion of Tuesday’s hearing, the Court directed Solicitor General Tushar Mehta and ASG S.V. Raju to conclude their arguments on merits. Guruswamy had not yet concluded her submissions on merits.

The matter has been posted to September 2, at the top of the board, at 2 PM.

Background

In May the Court had deferred the hearing until August 18 after indicating that the matter would be taken up after the partial working days period.

Earlier, in April , SG Mehta had told the bench that "The sitting Chief Minister has actively caused obstruction in investigation...Rule of Law ceases to operate when executive uses state machinery to obstruct investigation."

Previously, the Court had come down sharply on Mamata Banerjee over allegations that she interfered with an ongoing investigation, observing that such conduct “puts democracy in peril.” “This is not a dispute between the State and the Union,” the Bench had observed. “A Chief Minister of any State cannot walk into the midst of an investigation, put the democracy in peril, and then say don’t convert this into a dispute between the State and the Union,”
it said. The Court further remarked that such a situation was unprecedented and went beyond conventional federal disputes. “We never thought that in this country a day would come where a sitting Chief Minister would walk into the office where an investigating agency is probing a case,” the Bench said.
Earlier, the bench had raised sharp questions to the West Bengal government over its objection to the maintainability of a plea filed by the ED, asking whether officers of the agency cease to enjoy fundamental rights merely because they are government officials.

Court was hearing the plea filed by ED against the West Bengal Chief Minister and certain state police officers over their obstruction of a search at the office of political consultancy firm I-PAC. Recently, Senior Advocate Siddharth Luthra had told court that ED must justify how it has been weaponized in the state. In a sharp response, Additional Solicitor General SV Raju had said, "It has not been weaponized, it has been terrorized..".

In a complete reversal of her stance, Mamata Banerjee had told the Court that ED allowed her to retrieve devices and physical files during its search at the office of political consultancy firm I-PAC, which works with the All India Trinamool Congress.

On January 15, the court had issued notice on petitions filed by the Enforcement Directorate (ED) and its officers alleging interference by West Bengal Chief Minister Mamata Banerjee and senior state police officials during a search conducted at the office of political consultancy firm I-PAC and the residence of its director Prateek Jain.
