What did the court decide in Erickson v. Pardus?
Answered for: US
A document filed pro se is “to be liberally construed,” Estelle, 429 U. S., at 106, and “a pro se complaint, however inartfully pleaded, must be held to less stringent standards than formal pleadings drafted by lawyers,” ibid.
Decided weeks after Twombly, this per curiam opinion restated that the liberal-construction rule for self-represented filings remained in force. The sentence above is the court in its own words.
This answer is true in US and nowhere else on this site. Another jurisdiction is another answer, or an honest gap: see what has been read for US.
