From that link:

"In civil law countries, judges are often described as “investigators.” They generally take the lead in the proceedings by bringing charges, establishing facts through witness examination and applying remedies found in legal codes."

"In contrast, in a common law country, lawyers make presentations to the judge (and sometimes the jury) and examine witnesses themselves."

Also, asked my wife who is Scottish litigator:

Most law that is case law but not criminal legislation is civil law. We not have an inquisitorial system system but in practice judges do ask questions regarding legal submissions made by parties.
