What does "that" refer to?

Does "that" refer to the whole sentence underline as below?

That is, "that" = ""Judicial activism" is being likened to "legislating from the bench." In other words the assertion is being made that the rulings of certain "activist" judges amount to passing laws from the judicial seat of power, "the bench""?


Context:

"Judicial activism" is being likened to "legislating from the bench." In other words the assertion is being made that the rulings of certain "activist" judges amount to passing laws from the judicial seat of power, "the bench", that being a case of the judicial branch usurping the powers of the legislative branch of the government.

The idea does run throughout the entire passage quoted. But if I had to get specific, I would say that that "that" refers to "the rulings of certain "activist" judges amount to passing laws from the judicial seat of power."
