Can you use a non independent witness in court?

Yes, you can use a non-independent witness in court, but their testimony may be subjected to greater scrutiny. Non-independent witnesses, such as family members or close friends, may have biases or vested interests that could affect their credibility. The court may consider their relationship to the parties involved when assessing the weight of their testimony. Ultimately, it's up to the judge or jury to evaluate the reliability of the witness based on the context of their statements.
