Key legal question
Whether the municipal decision authorizing immediate road marking was void, so that obstruction of an official act could not be committed.
Extracted holding
The decision was defective but not void; it remained challengeable, and the official act was not absolutely ineffective.
Extracted reasoning
The omission to expressly state the suspension effect in the dispositive part was not a sufficiently grave, immediately recognizable procedural defect. The decision did not threaten legal certainty to a degree required for nullity.
