Graham Dwyer is challenging the use of his phone data as evidence, with implications for European data privacy rules
When Graham Dwyer was convicted of murder in 2015 it was a triumph for Ireland’s police and judicial system.
The architect had committed what prosecutors called “very nearly the perfect murder” but he was caught and sentenced to life in prison thanks to a meticulous investigation. Five years later, however, the conviction risks unravelling over the use of phone data – a twist that could see Dwyer walk free, and also have an impact on data privacy rules across Europe.
