In August 2015, the chief of the Enforcement Directorate issued a terse circular, one that turned conventional practice on its head. The ED, said acting director Karnail Singh, need not wait for other agencies such as the CBI to probe a case. If the courts have taken cognisance, ED can go ahead and start a probe on its own. In all its existence, ED, which comes under the purview of the Union finance ministry, has taken its cue from that “caged bird”, the Central Bureau of Investigation, which comes under the department of personnel (DoPT), which reports to the PMO.
