About this mock
This mock focuses on signature forensics and Indian documentary law: the four recognised forgery types (simulated, traced, freehand, and lifted), electronic signature forgery under BNS 2023 Section 336, the tracing indicators examined on the VSC-8000, and the admissibility framework under BSA 2023 Section 39. Questions test the precise one-parameter distinctions between simulated (model in view) and freehand (no model) forgery, between IPC 463 / BNS 336 (basic forgery), IPC 467 / BNS 338 (will and valuable security), and IPC 471 / BNS 340 (using a known-forged document), and between the five categories of expert opinion under IEA 45 / BSA 39.
The Indian case-law anchor is State of UP v Ram Babu Mishra (1980) 2 SCC 343 and Murari Lal v State of Madhya Pradesh (1980) 1 SCC 704, both Supreme Court rulings that established the standard for evaluating questioned-document expert opinion: relevant but not conclusive, requiring independent judicial assessment. The VSC-8000 examination of stroke sequence at ink-line crossings -- using UV fluorescence quenching and infrared luminescence to differentiate inks -- is covered in the final block. CFSL Kolkata's Questioned Documents Division and the Central Document Examination Laboratory (CDEL) are the primary reference institutions for Indian casework of this type.
Topics covered:
- Simulated, traced, freehand, lifted, and electronic signature forgery
- Traced forgery indicators: hesitation marks, uniform line width, absent pen lifts
- Signature classification: formal, cursive, initials, and mark types
- Genuine intra-writer variation and its range mapping
- BNS 336 / IPC 463: forgery definition and intent element
- BNS 338 / IPC 467: aggravated forgery of will and valuable security
- BNS 340 / IPC 471: using a known-forged document and knowledge element
- BSA 39 / IEA 45: expert opinion admissibility and the Ram Babu Mishra and Murari Lal rulings
Allow 30 minutes.
