Science, if understood and done correctly, does not lie. That is why science-baked evidence is your best offense or defense in litigation and criminal proceedings. Selecting the right expert witness for your legal matter is an important decision. It is imperative to select a subject matter expert that not only has the necessary experience and qualifications, but also has a demeanor that is engaging and can provide simplified explanations of technical matters.

Let’s discuss how Chemistry Matters can help with your litigation support needs

When should I hire an expert witness?

The simple answer is as soon as possible, especially if you think the analysis of data will become evidence or as part of a legal proceeding. In the most defensible situation,an expert witness should be part of the entire process from experimental study design, collection and analysis of appropriate samples and chemicals of interest, data interpretation and communication. However, the reality can be wide-ranging. Situations may develop when cases evolve towards litigation after routine collection of scientific data or you may be party to a complex proceeding where there is regulatory or third-party control over sampling design, sample collection and analytical programs. These situations still require forensic data analysis to identify limitations and data gaps.

Chemistry Matters provides expert support for all components of your case or investigation, which includes what happens before data is collected. We can provide statistical and defensible experimental/sampling design, improved chemistry data requirements, legal sampling advice or chain of custody execution, comprehensive data analysis and statistical interpretation, and visualization of results for effective communication. The Chemistry Matters team ensures that the full process is correctly performed and can stand up to legal scrutiny.
