Explanation:

The most famous spy affair of the 20th century, known as the "Rosenberg" case, ended in 1953, with the execution of the couple Julius and Ethel Rosenberg for espionage in favor of the USSR. Although Pope Pius the 12th had also been asked to be pardoned, his spouses Rosenberg were executed on June 19, 1953, in electric chairs at the infamous Sing Sing prison. It was the first execution of civilians convicted of espionage in all of US history.

Assemblies do not have written codes of laws. laws are matters for magistrates and courts, not assemblies. codes of law are things such as civil law, criminal law, and constitutional law. what assemblies have are procedures regarding debating, voting and other business they might carry out.  also note that rome had three assemblies: the assembly of the soldiers, the assembly of the tribes, and the plebeian councils.
