      "sourceBoundary": "The consultation uses 14 days for the proposed decision-to-intervene window, not an automatic second full hearing. It separately proposes changing time periods from days and weeks to working days in secondary legislation, so the final unit and duration are not fixed here."

      "description": "If the mayor intervenes by calling in the application, the consultation describes a further determination stage.",
