| EXAMINATION TARGET: | |
| Target Role: {target_role} (e.g., Complainant / Adverse Witness / Accused Drawer) | |
| CRITICAL INSTRUCTIONS FOR REALISTIC TRIAL CROSS-EXAMINATION: | |
| 1. DO NOT GENERATE MERE BULLET POINTS OR ISOLATED QUESTIONS. | |
| 2. Cross-examination in Indian Courts is an art of progressive entrapment based on PRIOR KNOWLEDGE and LEADING QUESTIONS (Sec 146 BSA). | |
| 3. Generate 1 or 2 high-impact interrogation chains (themes). Keep all fields concise, impactful, and under 25 words per step to fit strict token constraints. | |
| 4. Each chain MUST contain EXACTLY 4 sequential steps moving progressively: | |
| - Step 1 [Foundational Premise / Prior Knowledge]: Elicit an uncontroversial baseline admission based on undisputed facts, GST/ITR status, or previous statements. | |
| - Step 2 [Narrowing / Box-In]: Ask a leading question that eliminates room for subsequent excuses, alibis, or post-facto fabrications. | |
| - Step 3 [Confrontation with Evidence / Omission]: Spring the trap by confronting the witness directly with the uploaded instrument, ITR omission (Sec 269SS IT Act), ink disparity, or missing Sec 63 BSA certificate. | |
| - Step 4 [Statutory Trap / Final Suggestion]: Put the formal statutory suggestion to impeach the witness and enter the defense theory onto the trial record (Sec 139 NI Act / Sec 146 BSA). | |
| 5. For EVERY step, provide: | |
| - question (Must be a precise, leading courtroom question demanding an affirmative or trapped response) | |
| - prior_knowledge_grounding (The specific legal duty, admission, or document being leveraged) | |
| - expected_answer (The typical witness response) | |
| - advocate_notes (Strategic advice on why this step traps the witness) | |
| - pivot_if_hedged (Tactical follow-up if witness attempts to evade or qualify) | |
| 6. Include a Witness Credibility & Contradiction Scorecard: | |
| - Overall credibility score (0-100%, lower means more vulnerable to impeachment) | |
| - Risk level ("Critical Vulnerability", "High Risk", "Moderate Risk") | |
| - Statutory bars/pitfalls identified (e.g. Sec 269SS IT Act, Sec 63 BSA, Sec 87 NI Act) | |
| 7. Include Protective Examination-in-Chief Shield: | |
| - Exact clauses to insert into the friendly party's Evidence Affidavit (Order 18 Rule 4 CPC / Sec 145 NI Act) to preemptively survive these traps. | |
| 8. Include Presiding Magistrate / Judge Ruling Impact with landmark Supreme Court precedents. | |
| 9. Also include a backward-compatible "turns" array with 3 speaker turns (Petitioner, Respondent, Presiding Judge). | |
