What is a potential consequence of a conflict when a lawyer serves as both advocate and witness?

When a lawyer serves as both an advocate and a witness in a case, one of the potential consequences is indeed a risk of compromised effectiveness in representation. This dual role can create several issues, including a conflict of interest that may compromise the lawyer's ability to provide impartial and effective advocacy for their client.

For instance, if the lawyer's testimony contradicts or undermines their arguments as an advocate, it can weaken the client's case and potentially harm the outcome. The courtroom dynamic may also shift, as the lawyer's dual role could lead to perceptions of bias or confusion regarding their credibility. Additionally, ethical rules often advise against such situations to maintain the integrity of the legal process and protect clients' interests, further underscoring how serving in both capacities can detract from effective representation.

Understanding the implications of this scenario is crucial for maintaining professional ethics and ensuring that clients receive the best possible legal service, free from conflicts that might undermine their case.
