What did the court decide in Denton v. Hernandez?
Answered for: US
As we stated in Neitzke, a court may dismiss a claim as factually frivolous only if the facts alleged are "clearly baseless,"
The Court set the limits on dismissing an in forma pauperis complaint as factually frivolous. The sentence above is the court in its own words.
