The Lucas Direction and Parental Alienation

Here's an example of a case where the Lucas direction was used to assess the credibility and reliability of a child's testimony in a parental alienation dispute:

Case: Smith v. Johnson


In the Smith v. Johnson case, Sarah Smith and John Johnson were involved in a contentious divorce and custody battle over their 8-year-old daughter, Emily. Sarah alleged that John was emotionally abusing Emily and manipulating her against Sarah, while John claimed that Sarah was engaging in parental alienation, turning Emily against him without valid justification.

Court proceedings:

During the trial, Emily was called as a witness to provide her account of the situation. However, given her young age and vulnerability, the court determined that she needed special consideration when assessing her credibility and reliability. The judge decided to give the jury a Lucas direction to guide them in evaluating Emily's testimony.

Lucas direction implementation:

The judge instructed the jury using a Lucas direction, emphasizing the following points:

1. The need for caution: The jury was advised to exercise caution when evaluating Emily's testimony due to her age and potential vulnerability to influence from either parent.

2. Assessing coherence and consistency: The jury was instructed to consider whether Emily's testimony was coherent and consistent throughout her statements, focusing on any inconsistencies that may arise.

3. Evaluation of demeanor: The jury was told to pay attention to Emily's demeanor during her testimony, including her body language, tone of voice, and overall presentation, to assess her credibility.

4. External corroboration: The jury was reminded to consider any external evidence or supporting testimonies that could corroborate or contradict Emily's allegations.

5. Potential influence: The jury was advised to assess whether there was any evidence of parental alienation or manipulation present in the case, which could impact the reliability of Emily's testimony.


After considering all the evidence, including Emily's testimony, corroboration, and the presence of parental alienation dynamics, the jury reached a verdict that supported Sarah's claims of emotional abuse by John. The Lucas direction helped guide the jury in critically evaluating Emily's testimony while considering the potential influence of parental alienation.

It is important to note that each case is unique, and the application of the Lucas direction will depend on the specific circumstances and the discretion of the judge or jury involved.
