Calcutta High Court dismisses Criminal Revisional Petition, affirming that statutory presumption of hazard applies to illegal vertical expansion in congested urban areas without requirement for forensic proof
In a landmark judgment addressing the menace of unauthorized construction in congested metropolitan areas, the Calcutta High Court has upheld the conviction of developer Biplab Saha and property owner Shukla Das for erecting an unauthorized four-storied (G+3) building in violation of a sanctioned one-storied (G+1) municipal plan. Justice Uday Kumar dismissed the criminal revisional petition, holding that procedural irregularities in complaint initiation cannot vitiate a prosecution where substantive guilt is conclusively established through a full trial.
The case originated from a written complaint filed on February 12, 2017, by Sri Jayanta Paul, Assistant Engineer (Civil), Building Department, Borough-III of the Kolkata Municipal Corporation (KMC), alleging that the petitioners had constructed an unauthorized multi-storied building at premises no. 26/D, Dr. Panchanan Mitra Lane, Kolkata-700 085. The sanctioned building plan (B.P. No. 2015030090 dated March 31, 2016) restricted construction to the ground floor and first floor (G+1) due to narrow access passage constraints. The unauthorized expansion to four stories posed imminent threats to structural integrity, water supply, drainage, sewerage, road traffic, and fire safety.
The prosecution case proceeded systematically through investigation and trial. The learned Municipal Magistrate, 3rd Court, Calcutta, found both petitioners guilty under Section 401A of the Kolkata Municipal Corporation Act, 1980 (KMC Act), and sentenced them to three years rigorous imprisonment and Rs. 50,000 fine each on March 13, 2019. Upon appeal, the learned Additional Sessions Judge, Fast Track Court No. 2, affirmed the conviction but modified the sentence to simple imprisonment of three months for the developer and imprisonment till the rising of court for the property owner, both with Rs. 50,000 fine.
Arguments and Legal Issues
The petitioners challenged the conviction on multiple grounds. Through their counsel, Mr. Abhra Mukherjee, they argued that:
1. Procedural Defect in Initiation: The prosecution violated Section 620 of the KMC Act by proceeding without proper prior approval from the Municipal Commissioner or authorized officer.
2. Defective Service of Notice: Stop-work notices under Section 401 were allegedly served upon an unnamed mason rather than the owner or occupier in strict compliance with law, rendering the entire proceeding void ab initio.
3. Absence of Forensic Proof: The prosecution failed to establish actual danger through independent forensic evidence such as soil tests, structural stability audits, or external expert reports. The defense contended that without such scientific verification, there was no proof of actual hazard.
4. Insufficient Investigation: The defense highlighted the non-examination of the Ward Councillor who raised the initial grievance, the absence of seizure of building materials, and the lack of structural stability audits.
5. Sentencing Leniency: The petitioners sought the benefit of Section 360 of the Criminal Procedure Code or the Probation of Offenders Act.
The petitioners relied heavily on the decision in Mahendra Baid v. State of West Bengal (2025 SCC Online Cal 3666), arguing it established that procedural safeguards under Section 620 are mandatory and cannot be waived.
The Court's Analysis and Findings
Justice Uday Kumar meticulously examined three pivotal questions: (i) whether procedural defects vitiated the prosecution at inception; (ii) whether unauthorized construction was established beyond reasonable doubt; and (iii) whether concurrent findings suffered from illegality or perversity warranting revisional interference.
On Procedural Defects:
The Court held that while institutional initiation of criminal complaints requires proper administrative channelization, "technical arguments concerning internal file movements or initial authorization cannot override or vitiate a prosecution that has successfully traversed through a full-fledged trial where substantive guilt is established beyond reasonable doubt." The judgment distinguished the present case from Mahendra Baid, which involved a petition for quashing proceedings at the threshold under Section 482 of the CrPC concerning a minor internal modification (partition brick wall).
Justice Kumar noted: "Procedural technicalities at the threshold do not survive a completed trial where foundational guilt is thoroughly proved by robust ocular and documentary proof adduced during trial." The Court found that administrative steps taken by the municipal engineering department sufficiently satisfied the threshold for invoking criminal machinery, and any minor procedural imperfection was "fully cured by the substantive evidence adduced during trial."
On the Core Charge of Unauthorized Construction:
The prosecution relied on unrefuted testimonies from municipal engineering officials (Sub-Assistant Engineer, Assistant Engineer, Local Building Surveyor, and Executive Structural Engineer), the sanctioned building plan, and the Building Rule Infringement Statement. The Court found that the evidence conclusively established that the permissible height limit of 6.7 meters was grossly violated, with the structure exceeding authorized dimensions in front, side, and rear open spaces, Floor Area Ratio (FAR), and ground coverage.
The identity of the petitioners to the premises was conclusively established through the original development agreement and the property owner's admission during examination under Section 313 of the Criminal Procedure Code.
On the Statutory Presumption of Hazard:
The Court addressed the most significant legal issue: whether Section 401A requires actual forensic proof of danger or whether a statutory presumption applies. Section 401A provides: "any person who being responsible...constructs or attempts to so construct...any new building or additional floor...in contravention of this Act...as endangers or is likely to endanger human life, or any property of the Corporation..."
Justice Kumar held: "When an unauthorized multi-storey structure (G+3) is erected in a congested lane against a restricted G+1 sanction, the likelihood of hazard is a statutory presumption grounded in objective physical reality. The text of the statute uses the disjunctive expression 'endangers or is likely to endanger,' meaning actual structural collapse or post-facto forensic proof is not a mandatory prerequisite once illegal, unmonitored vertical expansion is proved from its inception."
The Court emphasized: "The physical reality of a towering illegal structure standing in a congested lane inherently creates the hazards contemplated by the legislature." Post-facto structural forensic audits or soil test reports are not mandatory once "the physical existence and illegal inception of an unmonitored high-rise expansion are conclusively proved through municipal records and ocular testimony."
On Revisional Jurisdiction:
Applying settled principles of criminal jurisprudence, the Court noted that revisional jurisdiction under Section 401 read with Section 482 of the CrPC is "extremely limited and not akin to a second appeal." Interference is warranted only when there is "a glaring defect, a patent perversity, or a gross miscarriage of justice resulting from a total misreading of the evidence on record."
The Court found no such defect. Both lower courts evaluated the evidence with care, and the defense adduced no oral or documentary evidence to challenge the overwhelming incriminating material. The concurrent findings were "firmly rooted in evidence and suffer from no perversity or illegality."
On Sentencing:
The Court commended the First Appellate Court for rectifying the Trial Court's excessive three-year sentence by applying Supreme Court sentencing jurisprudence from Soman v. State of Kerala (2013) 11 SCC 382 and Alister Anthony Pereira v. State of Maharashtra (2012) 2 SCC 648, which mandate proportionate punishment balancing deterrence and correction.
The appellate court correctly bifurcated culpability: treating the commercial developer (Biplab Saha) with strict deterrence through three months simple imprisonment plus Rs. 50,000 fine, while showing humane consideration to the passive property owner (Shukla Das) through imprisonment till rising of court plus Rs. 50,000 fine, accounting for her age and status.
Conclusion and Significance
Justice Uday Kumar dismissed the criminal revisional petition, affirming that unauthorized construction in violation of sanctioned municipal plans in congested urban areas—particularly when involving multi-storied unauthorized expansion—constitutes a serious offense attracting penal consequences under Section 401A. The judgment clarifies that:
1. Procedural defects at prosecution inception do not survive a full trial with substantive proof of guilt.
2. The "likelihood of hazard" under Section 401A is a statutory presumption grounded in objective physical reality when unauthorized multi-story structures are erected in violation of restricted sanctioned plans in congested areas.
3. Forensic proof, structural audits, or soil testing are not mandatory prerequisites for conviction under Section 401A.
4. Concurrent findings of lower courts cannot be interfered with in revisional jurisdiction absent glaring defects or perversity.
The judgment reinforces the judiciary's commitment to enforcing municipal building regulations as a matter of public safety and urban governance in metropolitan areas like Kolkata.
Bottom Line:
Unauthorized construction in violation of sanctioned municipal plans in congested urban areas, resulting in potential hazards to public safety and civic infrastructure, attracts penal consequences under Section 401A of the Kolkata Municipal Corporation Act, 1980. Procedural irregularities in complaint initiation do not vitiate a prosecution when substantive guilt is established through trial.
