An ECIR under the PMLA is an internal departmental document with no statutory status, so its quashing is not ordinarily maintainable unless the predicate offence itself is quashed; the challenge here was also premature because the alleged overlap with an earlier ECIR was not established. A subsequent ECIR or parallel investigation is permissible where it concerns a larger conspiracy, additional offences, or different accused, and is not barred as a second FIR. Statements recorded under Section 50 of the PMLA were not invalidated because Article 20(3), Section 164 CrPC safeguards, and Miranda-type protections apply only once a person is an accused or formally arrested. Section 50 summons and Section 66(2) information-sharing were upheld as part of lawful investigation, and a private person can be proceeded against for corruption-linked offences.
