Steps to Take If Your MMC Is Under Investigation

For merchant mariners, your Merchant Mariner Credential (MMC) is essential to your livelihood. If your credential is under investigation by the U.S. Coast Guard, it can put your career, reputation, and financial stability at risk. These investigations often involve serious allegations, and how you respond early on can significantly impact the outcome.


At Biggs & Gunst P.C., we understand what’s at stake. Our legal team is committed to helping mariners in Ann Arbor and across Michigan protect their credentials and navigate the investigation process with confidence.


Understand the Nature of the Investigation

The first step is to fully understand why your MMC is under investigation. The U.S. Coast Guard may initiate an investigation for reasons such as:

  • Alleged safety violations
  • Drug or alcohol-related incidents
  • Criminal charges or convictions
  • Misconduct or negligence

You may receive a formal notice outlining the allegations. It’s important to review this carefully and avoid making assumptions about the situation without proper legal guidance.


Do Not Ignore Official Notices

If you receive communication from the Coast Guard, do not ignore it. Deadlines and procedural requirements are strict, and failing to respond in a timely manner can negatively affect your case.


Taking prompt action shows that you are taking the matter seriously and helps preserve your ability to defend your credential.


Avoid Making Statements Without Legal Guidance

During an investigation, you may be asked to provide statements or documentation. While cooperation is important, anything you say can potentially be used against you.


Before providing detailed responses, it is wise to consult with a legal professional who understands MMC investigations. Biggs & Gunst P.C. can help you respond appropriately while protecting your rights.


Gather and Preserve Important Evidence

Start collecting any documentation that may support your case, including:

  • Employment records
  • Training certifications
  • Incident reports
  • Witness statements

Having organized and accurate information can make a significant difference in how your case is evaluated.


Understand Possible Outcomes

MMC investigations can lead to several outcomes, including:

  • No action taken
  • Warning or reprimand
  • Suspension of your credential
  • Revocation of your credential

Understanding these possibilities allows you to prepare and take proactive steps to protect your career.


Prepare for a Coast Guard Hearing

In some cases, your situation may proceed to an administrative hearing before a Coast Guard Administrative Law Judge. This is a formal legal process where evidence is presented and arguments are made.


Having strong representation during this stage is critical. Biggs & Gunst P.C. helps mariners prepare for hearings and presents clear, effective arguments on their behalf.


Take Steps to Protect Your Career

Even during an investigation, there may be actions you can take to strengthen your position, such as:

  • Completing additional training
  • Demonstrating compliance with regulations
  • Addressing any underlying issues related to the investigation

Our team at Biggs & Gunst P.C. can guide you on the best steps to take based on your specific situation.
