Quick Summary
Dr. Lorne Semrau (defendant) faced charges of healthcare fraud for upcoding services billed to Medicare and Medicaid. He sought to introduce expert testimony from Dr. Steven Laken regarding an fMRI-based lie detection test which indicated Semrau’s truthfulness about his billing intentions.
The district court excluded this evidence, Semrau was convicted, and he appealed on the grounds that the exclusion was an error. The appellate court affirmed his conviction, agreeing with the lower court’s decision to exclude the expert testimony based on Federal Rules of Evidence 702 and 403.
Facts of the Case
Dr. Lorne Semrau (defendant) was the owner and CEO of two companies that provided psychiatric care to nursing home patients. He was indicted on charges of healthcare fraud for allegedly upcoding services billed to Medicare and Medicaid, which involved using a higher-paying code on billing forms than the services rendered justified.
During his trial, Semrau sought to introduce expert testimony from Dr. Steven Laken, who had developed a patented fMRI-based lie detection test. Laken conducted three such tests on Semrau, with mixed results, but ultimately concluded that Semrau was generally truthful regarding his intent to bill services properly to Medicare.
The prosecution did not know about the test before it was conducted, which prevented them from contributing questions or observing the testing procedures. The results of the lie detection test became a central issue in the appeal after the district court excluded Laken’s testimony.

I.R.A.C. Format
Issue
Whether the district court erred in excluding expert testimony concerning fMRI-based lie detection results under Federal Rule of Evidence 702 and Federal Rule of Evidence 403.
Rule of Law
Expert testimony is admissible only if it is based on sufficient facts or data, is the product of reliable principles and methods, and the expert has reliably applied the principles and methods to the facts of the case, as per Federal Rule of Evidence 702. Additionally, evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, or misleading the jury, as per Federal Rule of Evidence 403.
Reasoning and Analysis
The appellate court reviewed the district court’s decision to exclude Dr. Laken’s fMRI-based lie detection testimony. The court considered whether the scientific evidence provided by Dr. Laken met the reliability and relevance standards under Federal Rule of Evidence 702.
It acknowledged that while fMRI technology can assess brain function, it has not been sufficiently tested in ‘real world’ legal settings, particularly with individuals accused of actual crimes. Furthermore, the court noted that Dr. Laken admitted to a significant false positive rate in his tests and that fatigue could affect accuracy.
In relation to Rule 403, the court noted constitutional concerns with admitting lie detection tests as they may unduly influence a jury’s assessment of witness credibility. Additionally, because the prosecution was not informed about the test beforehand, this could lead to unfair prejudice against them.
Due to these considerations, the court found that the district court did not abuse its discretion in excluding the evidence.
Conclusion
The appellate court affirmed Dr. Semrau’s conviction, upholding the district court’s decision to exclude Dr. Laken’s fMRI lie detection test results under Federal Rules of Evidence 702 and 403.
Key Takeaways
- Expert testimony must meet rigorous standards of reliability and relevance as outlined in Federal Rule of Evidence 702.
- Evidence that could unfairly prejudice or mislead a jury may be excluded under Federal Rule of Evidence 403.
- fMRI-based lie detection is not yet considered reliable evidence in ‘real world’ legal settings due to concerns about its accuracy and application.
