Join Resolution’s family law experts in our Podcast series

Each episode welcomes guest experts sharing their take on topical family law issues.  We cover the whole spectrum of family law, from abduction, surrogacy, and public law to financial remedy.

We invite our guests to take a deep-dive into a different topic each month.  On each episode we try and cover what is the current state of the law, or the leading authority, practical tips (if you are running one of these cases), and thoughts for reform.

Do expect some lively debates, and personal insights.  We try to find known experts in their field and ask them the things that we all want to know.  If you are an expert on a particular topic, either regionally or nationally, we would like to hear from you, so do please get in touch.

We were thrilled to be shortlisted for the Family Law Commentator of the Year award at the 2023 LexisNexis Awards.

S4 Episode 4: Hair Testing in the Family Court

About this episode

Hosted by: Anita Mehta and Simon Blain

Guests: Sarah Branson and Professor James Coulson

Further information
This month we are joined by Sarah Branson (Coram Chambers) and Professor James Coulson (Professor in Clinical Pharmacology and Toxicology at Cardiff University).

We discuss the concern that over-reliance on the numbers generated in hair testing can lead to miscarriages of justice.  The issue is that the use of a standardised cut-off levels have a racial bias, because the dark melanin in the hair helps to incorporate the drugs in the hair so someone with black hair will have a much higher reading than someone with red or blond hair, even if they have used the same amount of drugs over the same period of time.

Sarah recommends that from now on when hair testing is commissioned that it has to be instructed like other expert evidence – with a letter of instruction, there is a full forensic history.  Sarah has drafted a template LOI and order which you can access on the Coram website: https://www.coramchambers.co.uk/resources/hair-strand-testing-resources/

James makes the point that in other Courts (like to civil, criminal or coroners courts) it is unusual to have an analytical chemist commenting on the wider interpretation of the result.  James agrees that it is very important that evidence is not seen in isolation.  James takes us through the information that he would to see in these instructions in the future.

Sarah reminds us that we should start thinking about this evidence as expert opinion evidence rather than elevating the presumptive weight that should be given to the evidence.  Sarah directs us to the judgment of Lord Peter Jackson in D, Re (Children: Interim Care Order: Hair Strand Testing) [2024] EWCA Civ 498 (10 May 2024)

https://www.bailii.org/ew/cases/EWCA/Civ/2024/498.html.  Sarah points out the numbers from a test is the science but what those numbers mean is just someone’s opinion like any other expert evidence.
