What does "provided that" imply in relation to the salaries of the Judges mentioned in this text?
"Provided that" in this context implies that if a Judge of the Supreme Court at the time of his appointment is already receiving a pension (other than disability or wound pension) for any previous service under the Government of India, a State government, or any of their predecessor governments, then the judge's salary will be reduced. The reduction will be by the amount of that pension, and if they have also received the commuted value of the pension or a retirement gratuity in relation to that previous service, those amounts will also be deducted from the judge's salary for their service in the Supreme Court.
