Step 1: Understanding the Concept:
The question asks which authority has the power to determine the language of the subordinate criminal courts (courts other than the High Court) within a state.
Step 2: Detailed Explanation:
Section 272 of the Code of Criminal Procedure, 1973, is titled "Language of Courts." It states:
"The State Government may determine what shall be, for purposes of this Code, the language of every Court within the State other than the High Court."
This provision gives the exclusive power to the State Government to decide the official language to be used in all criminal proceedings in the subordinate courts (like the courts of Magistrates and Sessions Judges) within its territory. The language of the High Court is determined by separate constitutional provisions (Article 348).
The Central Government or the Supreme Court does not have a role in determining the language of subordinate courts in a state.
Step 3: Final Answer:
The State Government determines the language of all criminal courts within the state, other than the High Court.
