I am sorry, but the case information you provided is insufficient to create a case summary. The title "Section 18(2) in The Indian Evidence Act, 1872" is not a case title, but rather a section of a law. The court listed as "Union of India - Subsection" is not a valid court. The date "15 March 1872" is the date the Indian Evidence Act was enacted, not a specific case date.

To provide a proper case summary, I need the following information:

• Actual Case Name: (e.g., State of Maharashtra v. XYZ)
• Court Name: (e.g., Supreme Court of India, High Court of Delhi)
• Citation: (e.g., 2023 SCC Online SC 1234)
• Date of Judgment:
• A brief description of the facts and legal issues involved in the case.

Once you provide this information, I can create a summary following the requested format.
