Forensic Science Government Examiner of Questioned Documents
Definition
The Government Examiner of Questioned Documents (GEQD) is a forensic expert officially designated by the Government of India to investigate the authenticity of disputed documents. This role involves the scientific examination of handwriting, signatures, alterations, and print characteristics to uncover forgery, tampering, or manipulation. GEQDs operate as part of a national forensic system under the Ministry of Home Affairs, assisting in both criminal and civil cases by delivering expert analysis critical to the justice process.
History
- The study of questioned documents has a long history, going all the way back to the 3rd century A.D. Over time, it has developed with the help of both science and law.
- In India, the official role of Government Examiner of Questioned Documents (GEQD) was created during the time of British rule. This role was set up to help the police and courts check whether documents were real or fake.
- The first GEQD in India was appointed in Shimla in 1906 and worked under what is now known as the Bureau of Police Research and Development (BPR&D).
- Later, in 1949, S. N. Sen became the first Indian to hold this position, taking over from British experts like F. Brewster and R. Stott.
- As the need for document verification grew, new GEQD offices were opened in Kolkata, Hyderabad, and Shimla. These three centers became the main hubs for questioned document examination in India.
- Today, these offices work under the Directorate of Forensic Science Services (DFSS), which is part of the Ministry of Home Affairs, Government of India.
Locations
Shimla GEQD: Established in 1906, it is now part of CFSL Chandigarh.
Kolkata GEQD: Started in the 1960s, operates within CFSL Kolkata.
Hyderabad GEQD: Founded in 1968, it functions under CFSL Hyderabad.
Role of GEQD
- Acts as a government-appointed forensic expert for disputed documents.
- Supports law enforcement and courts by scientifically verifying document authenticity.
- Provides expert analysis and opinions on questioned writings.
Functions of GEQD
- Analyze handwriting and signatures to confirm origin or genuineness.
- Identify document tampering, including erasures and forgeries.
- Verify the legitimacy of important papers like wills and currency.
- Examine printing, typing, stamps, and seals for signs of manipulation.
- Assess ink and paper to help determine age and authenticity.
- Restore and interpret hidden or damaged text.
- Produce forensic reports and testify as expert witnesses in legal cases.
Essential Tools & Techniques in Forensic Document Examination
1.Visual & Optical Analysis Tools
To reveal fine details not visible to the naked eye, various optical instruments are employed in forensic document analysis.
Common Devices
Stereomicroscope
Allows detailed inspection of document surfaces. Helps in identifying trace marks, fiber damage, indentations, and line sequence (e.g., pen lifts or overlaps).
Comparison Microscope
Enables side-by-side comparison of handwriting, printed matter, or ink strokes under magnification.
Polarizing Microscope
Useful in identifying the optical properties of paper coatings or ink particles.
UV & Visible Light Sources
Emit light between 200 and 800 nm to detect hidden alterations, watermarks, or erased content under fluorescence.
Electron & Compound Microscopes
Employed when ultra-high magnification is needed for ink or paper surface analysis.
2.Imaging & Documentation Devices
Visual recording of evidence is critical before any physical or chemical testing.
Examples
Digital Cameras
Used to capture high-resolution images of documents and evidence locations.
Scanners
Provide detailed digital copies for analysis and archiving.
Magnifying Lenses
Quick,portable tools for on the-spot inspection.
3.Indentation & Impression Detection
Identifying pressure marks left from writing on overlying sheets can uncover valuable hidden content.
Key Tool:
Electrostatic Detection Apparatus (ESDA):
Detects non-visible indented writing without damaging the original document.
4.Ink & Paper Differentiation Systems
Used primarily to distinguish between different writing materials and detect modifications.
Specialized Instrument
Video Spectral Comparator (VSC)
- Analyzes documents under varying light sources to reveal differences in inks and paper types.
- Useful for spotting alterations, additions, or erased sections.
- While not suited for positive identification, it is excellent for comparative analysis
- While not suited for positive identification, it is excellent for comparative analysis.
5.Chemical & Analytical Techniques
Chemical processes assist in identifying the composition of inks, solvents, and paper treatments
Methods Include
Chromatographic Techniques (e.g., TLC)
Separate ink components to compare with reference samples.
Solvent Tests:
Used to dissolve and analyze inks or coatings.
Chemical Reagents:
Aid in detecting bleaching agents, ink age, or tampering.
Extraction Processes:
Remove specific components for further examination.
Fingerprint Bureau
Introduction
Establishment:
The Central Finger Print Bureau (CFPB) was established in 1955 as a national agency to manage fingerprint records and assist law enforcement in interstate criminal investigations.
Purpose:
Acts as the nodal agency for:
Tracking and locating interstate criminals
Standardizing and modernizing fingerprint bureaus
Facilitating coordination among state and national fingerprint agencies.
Need for Computerization:
Initiated to digitize fingerprint records at both state and national levels for effective record maintenance and crime coordination, including interstate and international offenders.
Historical Background:
The world’s first Fingerprint Bureau was set up in Calcutta in 1897. A CFPB was established in Shimla in 1905 but closed in 1922 following recommendations of the Inchcape Committee.
Relocation & Administrative Changes:
- Re-established in 1955 under the Intelligence Bureau, Delhi.
- Moved to Calcutta (now Kolkata) in 1956.
- Came under the Central Bureau of Investigation (CBI) in 1973.
- Since July 1986, it has functioned under the administrative control of the National Crime Records Bureau (NCRB).
Objectives of CFPB
- Keep fingerprint records of convicted persons.
- Identify unknown interstate suspects through fingerprint searches.
- Maintain and search prints of international criminals via Interpol.
- Examine disputed fingerprints on official documents.
- Train police and foreign personnel in fingerprint science under international cooperation schemes.
- Guide and coordinate State Fingerprint Bureaux.
- Hold the All-India Directors’ Conference on fingerprinting.
- Conduct annual certification exams for fingerprint experts.
