The Importance of Full Disclosure: How Hiding Evidence Can Backfire in Court

In litigation, honesty isn’t just ethical, it’s strategic. When parties fail to disclose relevant evidence, the consequences can be far more damaging than the evidence itself. Courts in Washington treat discovery violations seriously, and attempts to conceal or withhold information can lead to sanctions, loss of credibility, and even case-ending penalties.
At the Law Office of Erin Bradley McAleer, we emphasize one principle throughout every case: transparency builds trust with the court, the jury, and your own legal team. Discovery is not a game of hide-and-seek; it’s a process designed to ensure fairness and reveal the truth.
The Duty of Disclosure Under Washington Law
Under Washington Civil Rule (CR) 26(a) and the Federal Rules of Civil Procedure, parties must provide complete and accurate information during discovery. This includes producing all documents, digital data, and testimony relevant to the dispute.
The obligation doesn’t end with the initial disclosure. CR 26(e) requires ongoing supplementation—if new evidence arises or prior responses become incomplete, parties must update their disclosures promptly. Failing to do so can lead to severe procedural and reputational consequences.
What Happens When Evidence Is Hidden
Courts have broad authority to sanction discovery misconduct. Under CR 37 and its federal counterpart, a judge may impose penalties when a party intentionally withholds or destroys relevant material. Possible sanctions include:
- Exclusion of evidence at trial,
- Adverse inference instructions allowing the jury to assume the hidden evidence was unfavorable,
- Monetary sanctions or attorney’s-fee awards, and in extreme cases,
- Dismissal or default judgment.
The Credibility Cost
Beyond court sanctions, concealment severely damages a party’s credibility. Once a judge or jury learns that evidence was withheld, every statement that follows is viewed with suspicion. The loss of trust can be fatal to a case, no matter how strong the facts might otherwise be.
For attorneys, discovery abuse risks professional discipline. The Rules of Professional Conduct (RPC 3.3 and 3.4) impose duties of candor to the tribunal and fairness to opposing counsel. Violations can result in sanctions from the court or referral to the state bar for disciplinary review.
Ethical Advocacy and Strategic Transparency
Full disclosure doesn’t mean surrendering your case, it means presenting it honestly and strategically. Effective advocacy involves anticipating what opposing counsel will seek, addressing weak points early, and ensuring the court sees that your position is supported by complete, credible evidence.
At the Law Office of Erin Bradley McAleer, we approach discovery as both a legal and ethical responsibility. Our attorneys ensure that clients meet their obligations while protecting privileged communications, sensitive data, and privacy interests through appropriate protective orders under CR 26(c).
How Attorneys Prevent Discovery Violations
A proactive discovery strategy reduces risk and strengthens outcomes. Our approach includes:
- Early case assessment to identify all relevant evidence;
- Preservation protocols for electronic and physical documents;
- Thorough review and production of responsive materials; and
- Regular client communication to update disclosures as new facts emerge.
These steps maintain compliance, protect credibility, and build a foundation of integrity that resonates with courts and juries alike.
The justice system depends on honesty. Attempts to conceal or manipulate evidence often cause more harm than the truth ever could. Courts in Washington expect—and enforce—complete transparency during discovery, and violations can undo months or years of work in a single ruling. At the Law Office of Erin Bradley McAleer, we help clients navigate discovery obligations with precision, integrity, and strategic foresight. Our goal is simple: present the strongest possible case built on credibility, compliance, and truth
