Some successful cases

New success case from SMK Lawyers in defending companies accused in criminal proceedings for workplace accidents resulting in worker fatalities.

Acquittal for our client accused of driving under the influence of alcohol
In August 2022, our client was stopped by the Mossos d’Esquadra and charged with driving under the influence of alcohol. SMK Lawyers, represented by Sergi Mercé Klein, argued that the positive result was due to the interaction between alcohol and the client’s medication. Ultimately, Criminal Court No. 1 of Barcelona acquitted him.

Our client was acquitted of a sexual assault charge
This verdict, issued by the Provincial Court of Barcelona, represents another success for SMK Lawyers in defending individuals falsely accused of sexual assault, once again demonstrating that the accusation against our client was unfounded and that the alleged incident never took place.
