IMPORTANT POINT
Every judge who presides over a criminal trial, has authority and duty to decide on validity or relevance of questions asked of witnesses. Courts in all criminal trials should, at beginning of trial, i.e. after summoning of accused, and framing of charges, hold a preliminary case management hearing.

Certainly. Here are the key points derived from the legal document:

• The Supreme Court emphasized that every judge presiding over a criminal trial has the authority and duty to decide on the validity or relevance of questions asked of witnesses (!) .
• All criminal trials should begin with a preliminary case management hearing immediately after framing charges, to consider the total number of witnesses, classify them, and decide on admissibility of documents (!) (!) .
• Courts should consider whether parties can admit any documents at the preliminary stage, with exercise of admission/denial under specific procedural provisions (!) .
• The schedule for recording witnesses should be fixed with consecutive dates, and witnesses may be bound down for multiple days if necessary; fixed dates should accommodate non-appearance or inability to examine witnesses (!) (!) .
• The practice of recording depositions should follow a structured format, with witnesses numbered systematically (PW-1, PW-2, etc.), and depositions divided into paragraphs with clear attribution of date and examination type (!) (!) (!) .
• Exhibits should be marked systematically (Exhibit P-1, P-2, etc. for prosecution; D-1, D-2, etc. for defense; C-1, C-2, etc. for court), with clear indication of the witness through whom the exhibit was introduced (!) (!) .
• Material objects shall be marked sequentially (MO-1, MO-2, etc.) (!) .
• After framing charges, references to accused, witnesses, exhibits, and material objects should be by their assigned numbers rather than names, except during identification or if witnesses are not examined (!) (!) .
• Statements recorded under Sections 161 and 164 of the Cr.P.C. should be marked by extracting relevant portions, with clear marking to prevent inadmissible parts from entering the record (!) (!) (!) .
• Only admissible portions of confessional statements should be marked and properly extracted for evidence (!) .
• Every judgment must contain a preface with party names, a tabular statement, and an appendix listing witnesses and exhibits, along with reasons for decisions, and details of the offense and sentence if applicable (!) (!) (!) (!) (!) (!) .
• In judgments, references to parties, witnesses, exhibits, and objects should be by their assigned numbers or nomenclature, not solely by names, with numbers in brackets for identification (!) .
• Judgments should be organized into numbered paragraphs, possibly divided into sections, to ensure clarity (!) .
• The process for bail applications in non-bailable cases should be expedited, with reasons for delays provided if they occur (!) .
• The separation of prosecutors from investigators is mandated, with advocates appointed to advise during investigation (!) (!) .
• Trial proceedings should be conducted expeditiously, with a schedule of consecutive dates fixed after a preliminary hearing, and cases should be prioritized to avoid unnecessary postponements (!) (!) (!) .
• The trial process should include a formal, detailed record of the investigation, including body sketches, photographs, videos, and scene mahazars, with specific procedures for their preparation and preservation (!) (!) (!) (!) (!) (!) (!) (!) (!) (!) (!) (!) (!) (!) (!) (!) (!) (!) (!) .
• The supply of documents to the accused should include statements, lists of exhibits, and material objects, with clear identification of those relied upon and not relied upon by the prosecution (!) .
• The recording of evidence should be in a typed format, with simultaneous translation where necessary, and depositions should be read over in court with copies provided to parties (!) (!) .
• Witness depositions should be systematically numbered, with clear indication of the examination stages (!) .
• Exhibits should be systematically marked and referenced with their associated witnesses (!) (!) .
• After framing charges, references to witnesses and exhibits should be by their assigned numbers, and references to statements under Sections 161 and 164 should be carefully marked to avoid inadmissible material (!) (!) (!) .
• Judgment writing should follow a structured format, including points for determination, reasons, and separate treatment of each accused if multiple are involved (!) (!) (!) (!) (!) .
• The rules aim to streamline and standardize procedures to reduce delays, improve clarity, and ensure fair trial practices across jurisdictions (!) (!) (!) .
• The implementation of the draft rules requires expeditious action by high courts and state authorities, including amendments to existing manuals and notifications within six months (!) (!) .
• The court appreciates the contributions of legal professionals and amici curiae for their valuable inputs in formulating these guidelines and rules (!) .
