Questão jurídica principal
Whether the appellant had standing to invoke arbitrary application of watercourse setback rules.
Decisão extraída
He lacked standing because those setback provisions protect public interests, not neighbor-specific interests.
Fundamentação extraída
The challenged watercourse-distance rule serves flood protection, water and bank protection, and hydraulic works; it is not a norm protecting neighbors within the meaning of art. 88 OG.
