Scope: A deeply reported explainer on the alleged tampering of DNA/forensic reports at Forensic Science Laboratory (FSL), Rohini, Delhi), the Delhi High Court’s 2018 order that triggered a CBI probe, and the 2019 FIR against two FSL officers. Packed with dates, case names, primary orders, and policy takeaways.
In-depth analysis of the self acclaimed Guardian ofForensic Science and their Opression to Forensic Community
What the High Court saw (Aug 7, 2018):
While hearing the State’s appeal against a trial-court acquittal of Khursheed (POCSO rape of an 8‑year‑old), the Delhi High Court recorded that an FSL DNA report on the victim’s underwear claimed “no match” with the accused’s blood sample. The bench (Justices Vipin Sanghi and P.S. Teji) found “something amiss,” especially because the mother’s testimony and medical evidence pointed to guilt. The court noted the FSL report wasn’t even exhibited at trial, and when original records reached the HC, the seal on the envelope of worksheets was broken — stunning for an agency that routinely handles sealed exhibits.
Order highlights: the court could not treat incorrect reports as bona fide mistakes; compromised samples or manipulated reports could not be ruled out; and “outsiders/touts” may be involved. The court therefore ordered a CBI preliminary inquiry into FSL’s working, especially DNA reports and all reports prepared by Ms. L. Babito Devi.

Outcome in Khursheed: On fresh sampling under court supervision, new DNA results matched the accused, reversing the acquittal.

Regular Case (RC): RC0032019A0033, registered by CBI (ACB/Delhi) on September 27, 2019.
Accused (then posting):
Allegations: The duo prepared false/incorrect opinions and tampered with forensic exhibits in three Delhi Police cases (2012–2013), which initially led to favourable lower-court outcomes for the accused. On re-examination, experts from FSL Rohini (other scientists) and CFSL (CBI), New Delhi contradicted their opinions.
Key specifics from the FIR and press summaries:
Records-handling lapses: The FIR notes non‑preservation of exhibits and electropherograms — a basic breach of DNA-reporting practice.

Is there a conviction against the FSL officers yet?
Open‑source reporting captures the FIR registration and probe; any subsequent chargesheet/trial outcomes should be checked on CBI case status or court e‑filing portals. (If you need, I can add a live tracker section.)
Does this mean all FSL Delhi reports are unreliable?
No. The HC singled out specific irregularities and directed systemic checks. But the episode underscores why chain‑of‑custody discipline and blind/unbiased analysis are non‑negotiable.
Where can I learn the forensics basics?

This guide sticks to primary orders and mainstream reportage. If you come across later orders/chargesheets in this matter, share the links and I’ll expand the tracker with case numbers, next dates, and filings.
