Indirect speech:
The judge asked the lawyer if/whether he would be able to complete his arguments the next day.
Explanation:
The dialogue inside the inverted comma is a interrogative sentence or a question being asked by the Judge to the lawyer, the reporting verb 'asked' will be used.
And as the reporting verb is in past tense, the main verb will also be converted to past tense. The time mentioned 'tomorrow' will change into 'next day'
