Background
Dominic Lawson is a journalist and columnist who has served as editor of The Spectator and editor of the Sunday Telegraph before moving to his current role as a weekly columnist for The Sunday Times. He is the son of Nigel Lawson, Chancellor of the Exchequer under Margaret Thatcher. Over a long career in print journalism he has written on political, cultural and social matters with a particular interest in questions of scientific and statistical reasoning, including the challenges that probabilistic evidence poses for courts, juries and public understanding. He has noted in published pieces that a sister, Rosa, died in infancy, an experience he has described as informing his engagement with cases involving the deaths of very young children.
Commentary on the Letby case
Lawson has written a number of pieces in The Sunday Times engaging critically with the safety of Lucy Letby’s convictions. His commentary has focused primarily on the statistical dimension of the prosecution case: the use of the association between Letby’s shifts and the timing of collapses and deaths as a pillar of the evidence against her. He has drawn attention to the work of statisticians and mathematicians who have argued that the statistical reasoning presented to the jury at trial was flawed or misleading, and has noted that the history of expert-evidence-dependent prosecutions in England and Wales contains several cases where convictions subsequently proved to have rested on unreliable scientific testimony. His columns have been notable for their willingness to engage with technical statistical arguments and to translate them into terms accessible to a general readership.
On the Sally Clark parallel
A central thread of Lawson’s Letby commentary has been the parallel with the Sally Clark case. Clark, a solicitor convicted in 1999 of murdering her two infant sons, had her conviction quashed in 2003 after it emerged that the prosecution had relied in part on flawed statistical evidence from Professor Sir Roy Meadow, who had claimed that the probability of two cot deaths occurring naturally in the same family was approximately one in 73 million — a figure that reflected a fundamental statistical error. Lawson has argued that the statistical reasoning employed in the Letby prosecution is vulnerable to analogous criticism: that it treats the association between a nurse and adverse events as evidence of causation without adequately accounting for confounding factors or the base rates of serious clinical deterioration in a premature-infant population. He has used the Clark parallel not to assert that Letby is innocent but to argue that the conviction deserves the kind of rigorous post-conviction scrutiny that the Clark case eventually received.
