Forbes asks whether Argentina is using quid pro quo to convince other countries to file amicus briefs in an upcoming Supreme Court case against its bondholders:

However, there are some indications that Argentina has paid for one or more of the anticipated amicus filings. The Supreme Court takes a dim view of that practice; it wants each amicus filer to truly be a “friend of the court,” not a “friend of a party.” The Court does not strictly prohibit the filing of amicus briefs that have been paid for by a party. But it requires that the fact of payment be explicitly disclosed in the opening footnote of the amicus brief.
