I could not find an answer in online dictionaries. Why it is considered general reference?
In some English-speaking countries (for example the US) "the government" always includes the courts, since the US constitution specifies that the courts are one of the three branches of the government. That is a legal determination, though, not a linguistic one.
And in other English-speaking countries, "the government" does not include the courts in certain contexts - in particular, "the government" in the UK usually refers to the currently ruling party and its ministers. In other English-speaking countries there might be yet other answers, depending on the political or legal system. Your question cannot be answered on a language basis, only a political or legal basis, and can be found in any basic reference on the particular country in question.
