10. SPECIAL CONSIDERATIONS FOR MARYLAND
10.1 OAH Procedures
The OAH is the central hearing agency for Maryland and handles contested cases for over 30 state agencies. Key considerations:
- Subpoena forms are available from the OAH
- The $5.00 fee per subpoena must be paid at the time of the request
- The 15-day advance request rule is strictly enforced
- Witness fees must be paid in accordance with Md. Code, Cts. & Jud. Proc. § 9-202
10.2 Statewide Uniform Subpoena Form
Maryland uses a statewide uniform subpoena form for both court and administrative proceedings. Ensure that the subpoena received conforms to the approved form.
10.3 Public Information Act Considerations
Some documents sought by administrative subpoena may also be subject to the Maryland Public Information Act (Md. Code, Gen. Prov. §§ 4-101 to 4-601). Consider whether production in an administrative proceeding could result in broader public disclosure.
10.4 HIPAA and Medical Records
For subpoenas seeking medical records or PHI:
☐ Determine if a HIPAA-compliant authorization is attached
☐ Assess whether a qualified protective order is needed
☐ Provide required notification to the patient/individual if applicable
☐ Ensure compliance with both HIPAA and Maryland medical records statutes
10.5 State Employee Witnesses
Under Maryland law, State officials or employees who are subpoenaed:
- Are not entitled to witness fees
- Receive their normal salary during witness days
- Are not required to take annual leave for witness days
- Must still comply with the subpoena

About This Template
Administrative law covers how you interact with government agencies, from filing a comment on a proposed rule to appealing a denied license or benefit. Agency processes have their own forms, deadlines, and evidence standards that are different from what courts use. Getting the paperwork wrong usually means missing a deadline or losing the right to appeal, so precision in these documents matters as much as it does in a courtroom filing.
Important Notice
This template is provided for informational purposes. It is not legal advice. We recommend having an attorney review any legal document before signing, especially for high-value or complex matters.
