Key legal question
Whether the public-law appeal was admissible despite Article 83 lit. k BGG and no enforceable entitlement to the subsidy.
Extracted holding
The appeal was admissible because the case concerned a partial revocation/reduction of an already granted subsidy, which affects the recipient's legal position.
Extracted reasoning
Although subsidies without a legal claim are generally excluded, a challenge to a withdrawal or reduction of an existing grant is reviewable because it interferes with acquired rights.
