Why a Conviction Isn’t the End: Two Cases That Prove You Should Never Give Up

Being convicted of a crime after a trial can feel like the end of the road. But in reality, it often isn’t. Appellate courts regularly review trial records for serious legal errors, and when those errors affect fairness, convictions can be reversed and cases sent back for a new trial.

Two California cases—In re Melson and People v. Deen—show exactly why experienced legal representation after a conviction can make a critical difference.

Our experienced criminal defense attorneys at Wallin & Klarich can guide you through the legal process. Call Wallin & Klarich today toll-free at (877) 466-5245 for your free consultation with one of our criminal defense attorneys near you.

False Testimony Can Overturn a Conviction: In re Melson

In In re Melson, Alonzo Melson was convicted of a gang-related shooting largely based on eyewitness testimony. But at retrial, the prosecution’s key witnesses offered new and damaging details that were never mentioned in earlier statements to police.

One witness falsely claimed he had previously told police about identifying a facial tattoo. Another insisted she had identified Melson in photo lineups during police interviews—something that never happened.

Even more concerning, the prosecution did not correct these false statements and relied on them during closing arguments.

The California Supreme Court reinforced a crucial rule: when false testimony is allowed to stand uncorrected, a conviction must be reversed if the testimony may have influenced the verdict. The prosecutor’s intent is not the focus—the fairness of the trial is.

Because the false testimony was material and uncorrected, Melson’s conviction was overturned.

A Biased Juror Can Invalidate a Trial: People v. Deen

In People v. Deen, the issue was not false testimony but juror bias.

During jury selection, a prospective juror admitted knowing one of the victims, a police chief, and having been exposed to case-related information through law enforcement contacts. Despite acknowledging a friendship, the juror insisted he could remain impartial.

The defense asked that the juror be removed for cause. The trial court refused, believing it lacked authority because the juror claimed he could be fair.

On appeal, the court clarified the law: judges are not bound by a juror’s self-assessment of impartiality. If actual bias exists—or if circumstances suggest bias—the court has authority to excuse the juror.

Because the trial court applied the wrong legal standard, Deen’s conviction was reversed.

What These Cases Teach Us About Criminal Convictions

Both Melson and Deen highlight an important truth: criminal trials are not immune from serious error.

Mistakes can occur in many forms, including:

  • False or misleading testimony
  • Failure by prosecutors to correct known inaccuracies
  • Improper juror selection
  • Misapplication of legal standards by trial courts

When these errors affect the fairness of a trial, appellate courts have the power to step in and order a new trial.

Why Post-Conviction Representation Matters

After a conviction, the legal fight becomes more technical—and more challenging. Appeals are not about retrying the case; they are about identifying legal errors in the trial process itself. That requires a deep understanding of trial records, procedural rules, and appellate standards.

This is where experienced criminal defense attorneys play a critical role.

How Wallin & Klarich Can Help After a Conviction

At Wallin & Klarich, we understand that a conviction is not necessarily the end of your case. Our attorneys regularly handle appeals, habeas corpus petitions, and post-conviction motions designed to correct serious legal errors.

We assist clients by:

Identifying Trial Errors

Our team carefully reviews transcripts, evidence, and court rulings to identify constitutional violations, improper jury selection, prosecutorial misconduct, or evidentiary errors that may have impacted the verdict.

Filing Appeals and Writs

We prepare and file detailed appellate briefs and habeas petitions that explain why a conviction should be reversed under California and federal law.

Challenging Unfair Convictions

When false testimony, juror bias, or procedural mistakes have affected a case, we fight to have the conviction overturned and a new trial ordered.

Preparing for a New Trial if Granted

If a case is reversed, we are prepared to immediately step in and defend you in a new trial with a stronger, more strategic defense.

Guiding Clients Through Complex Post-Conviction Rules

Post-conviction relief is highly technical and time-sensitive. We guide clients through deadlines, procedural requirements, and strategic decisions every step of the way.

Don’t Assume a Conviction Is Final

Cases like In re Melson and People v. Deen show that even after a conviction, the legal system provides safeguards to correct injustice. But those safeguards only work when they are properly pursued.

If your trial was affected by false evidence, juror bias, or legal error, you may have grounds to challenge your conviction.
