The Trap Case and the Disproportionate Assets Case Compared

These are the two kinds of case the Act produces, and they have almost nothing in common beyond the forum. A trap case is an event: it is investigated in a day, tried on the evidence of three or four witnesses, and decided on whether a demand was proved. A disproportionate assets case is a reconstruction: it takes months to investigate, years to try, rests on documents and valuations, and is decided on arithmetic. The differences run through the investigation, the evidence, the defence and the outcome.

1. The Comparison

Basis	Trap case	Disproportionate assets case
The offence	Section 7, and Section 8 against the giver	Section 13(1)(b)
What is proved	A demand and an acceptance at a moment in time	A state of affairs over a period of years
How it begins	A complaint from the person from whom the demand was made	Source information, a search, or material thrown up by another case
Prior approval	Not required; the exception for arrest on the spot applies	Not ordinarily required, the wealth not being relatable to a particular decision
Rank of investigator	As Section 17 prescribes	The same, with the additional order of a Superintendent of Police
The evidence	The complainant, the shadow witness, the panch witnesses, the recovery, the washes and any recording	Property documents, bank records under Section 18, valuations, service records and estimates of expenditure
The presumption	Section 20 operates once acceptance is proved	The burden of accounting arises under the Explanation to Section 13(1)(b) once the foundational facts are proved
The usual defence	No demand; money thrust; payment for a lawful reason	The check period is wrong; the valuation is inflated; the sources were lawful
Why it fails	The complainant turns hostile and the shadow witness heard nothing	The computation is not proved with precision, or the disproportion is small
Punishment	Three to seven years and fine	Four to ten years and fine

2. The Different Skills They Require

A trap is an operation. It depends on planning, on independent witnesses, on placing the shadow witness where he can hear, and on contemporaneous records made within hours. Everything that can go wrong goes wrong on the day.
A disproportionate assets case is an audit. It depends on choosing a defensible check period, on obtaining complete bank records, on valuing property on evidence rather than assumption, and on estimating expenditure conservatively. Everything that can go wrong goes wrong in the computation.
The cross-examination differs entirely. In the first the defence attacks the witnesses; in the second it attacks the figures, usually with a valuation of its own.
The defence preparation differs. A trap is answered by an explanation offered at once; an assets case is answered by documents assembled over months showing lawful sources.

⚠ Why the two are often found together

A search conducted after a successful trap commonly discloses assets beyond the officer's known means, and the agency then registers a second case. The material overlaps: the gifts and payments proved in the first appear as unexplained receipts in the second, and a conviction in either strengthens the other. Conversely a defence that succeeds in the trap case, by showing that the money was a repayment of a loan, may create a difficulty in the assets case, where the same loan must then be accounted for as a liability. Advising on the two together, rather than separately, is what a practitioner is paid for.

3. Common Ground

The same forum. Both are tried by the special judge, on the warrant case procedure, without committal.
The same sanction requirement under Section 19 before cognizance.
The same attachment exposure under Section 18A and under the money laundering legislation.
The same appellate route, directly to the High Court under Section 27.
The same relationship with departmental proceedings, which may run in parallel on the same facts.
