Sentence:  Until recently Denmark hesitated to adopt a formal <WSD>per se</WSD> law, preferring to give more discretion to its judges, but the general practice was to take blood tests and to convict those accused under the classical law if the blood alcohol concentration was greater than 100 mg./100 ml. 
Meaning of the word marked with <WSD> tags:  Not leaving discretion to the judge to take into account additional factors that could rebut the judgment, deriving the qualification from the statute.
