Question juridique clé
Whether revision under Art. 121 lit. d LTF could be granted because the Court overlooked a relevant fact in the file.
Solution extraite
The omitted second letter was not a relevant fact; even if considered, the previous irreceivability ruling would have been unchanged.
Motifs extraits
The second letter was unclear, lacked conclusions and the challenged cantonal decision, and did not meet the formal requirements of Arts. 116, 106(2) and 117 LTF.
