Questione giuridica chiave
Whether revision was justified under Art. 121 let. d LTF because the Court allegedly overlooked a relevant filing.
Decisione estratta
The omitted letter was not a relevant fact within the meaning of Art. 121 let. d LTF, because knowledge of it would not have changed the inadmissibility decision.
Motivazione estratta
The second letter was unclear, lacked proper conclusions and identification of the cantonal decision challenged, and did not meet the requirements of Arts. 116, 106(2), and 117 LTF; the same inadmissibility result would therefore have followed.
