Key legal question
Whether the civil complaint against the possessory protection judgment was admissible and sufficiently substantiated under constitutional review limits.
Extracted holding
The complaint could be examined only as a constitutional challenge; insofar as it relied on ordinary federal-law arguments or unsubstantiated factual attacks, it was inadmissible or failed.
Extracted reasoning
Possessory protection is a protective, provisional measure; therefore only constitutional rights may be invoked. The municipality did not adequately allege arbitrariness or otherwise meet the substantiation burden.
