Federal Cases

Federal Criminal Cases are among the most difficult to defend. The complexity of these cases are high and the stakes are higher. If you are under investigation or under indictment for a federal crime, you need a lawyer representing you who is both familiar and comfortable with the very specific rules and formalities a federal charge brings with it. Whalen Law Office has decades of experience in the Federal Court system and a proven track record of results for clients facing the most serious of Federal offenses.

State Cases

When the State of Texas brings criminal charges against an individual, the charges can be classified as a misdemeanor or a felony. The range of punishment is very wide, and no two cases are exactly the same. Whether you are facing a Class C Misdemeanor that is punishable by fine only, or a capital charge that could result in a life sentence, you can rest assured that Whalen Law Office has tried similar cases and has the knowledge and experience to get the best possible results for you or your loved one.

Appellate Cases

A loss at the trial level is not the end of a criminal case. Every defendant has certain right to appeal the decisions made or the job done by their previous lawyer. However, appeals are difficult, complicated and the rules are generally unbending. If you or someone you know wishes to appeal a previous court ruling, a conviction, or a sentence, Whalen Law Office can help navigate you through the issues you will face.
