Under Rule 3.4, what action is prohibited for lawyers in relation to evidence during discovery?

The prohibition under Rule 3.4 specifically prevents lawyers from obstructing access to evidence or tampering with documents. This rule emphasizes the importance of honesty and integrity in the legal profession. Lawyers have an ethical obligation to ensure that the discovery process is fair and transparent. Tampering with evidence or obstructing access is not only unethical but also undermines the legal system’s integrity.

The other options outline actions or obligations that do not align with the ethical standards set by the rules. Altering evidence, regardless of the perceived benefits to a client, is impermissible and violates professional conduct standards. Providing only evidence that supports a case could lead to selective disclosure, which is misleading and unethical. Additionally, while there are obligations to comply with requests for evidence, these requests must also be within the bounds of legal and ethical practice, which does not equate to an absolute requirement to comply under all circumstances. Therefore, the correct understanding of Rule 3.4 focuses on the prohibition against obstruction and tampering, which serves to uphold the integrity of the legal profession and the judicial process.
