Perhaps you should try some spelling variations:
"transnational politics" » "international politics", "national politics"
"transnational justice" » "transitional justice", "organizational justice"
"international justice" » "international joint"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("transnational justice") OR ("international justice"))) OR ("transnational politics"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"transnational justice\") OR (\"international justice\"))) or (\"transnational politics\"))*".
• Removing quotes may allow a broader search: (((( transnational justice ) OR ( international justice ))) or ( transnational politics ))*.
