Questão jurídica principal
Whether the federal complaint against the cantonal appellate decision on marital protection measures was admissible and reviewable only for constitutional violations.
Decisão extraída
The complaint was admissible as a civil-law appeal, but in this interim-mesures context only constitutional rights could be invoked; the strict substantiation requirement applied.
Fundamentação extraída
Eheschutz decisions are provisional measures under Art. 98 BGG, so the Federal Court reviews only properly substantiated constitutional complaints and does not enter on merely appellatory criticism.
