(From The Wrecker by Robert Louis Stevenson and Lloyd Osbourne, Chapter XVII, published 1892)[1]passage 271

“It would have weight with me, doctor,” I replied.
“I may go further,” he pursued. “Suppose I had been there, or you had been there. After a certain event had taken place, it's a grave question what we might have done—it's even a question what we could have done—ourselves. Or take me.

I've looked up the meaning of 'judicial' in the dictionaries https://www.collinsdictionary.com/dictionary/english/judicial but I'm not certain what is meant in this context. In particular the combination with the word 'emphasis' troubles me. Is there a synonym?
