This comment addresses the incorrect treatment and presentation of data from laser ablation ICP-MS U–Pb age determina-tions of two samples of the Třebíč Pluton. This results in inaccurate ages and error assessment, invalidating the age inter-pretations of the authors. To corroborate our arguments, new high-precision chemical abrasion ID-TIMS data are presented that unequivocally define the emplacement age of the Třebíč pluton.
