Key legal question
Whether X. had standing to appeal the acquittal as an injured party without having asserted civil claims in cantonal proceedings.
Extracted holding
He lacked standing because he did not, to the extent reasonably expected, assert quantified civil claims in the cantonal proceedings and did not explain in his federal appeal why he had refrained from doing so.
Extracted reasoning
Standing under Art. 81 para. 1 let. b ch. 5 LTF requires that the challenged decision may affect civil claims. After the 2011 amendment extending standing to the complainant, the prior case law remains applicable: where no civil conclusions were taken below, the appellant must explain the claims, the impact of the decision, and the reasons for not acting earlier. X. did none of this.
