I've only heard it used up til now as "pettifogging details"---it is a cool word, has a Dickensian ring to my ear.
Yes, I'm sure it's Dickensian - IIRC original meaning was raising trivial objections so as to slow down opponent's case in court and, judging by Bleak House where a law case lasts over 20 years, those lawyers must have been pretty good at it! Again IIRC, a similar word is chicanery. Chicanes are used in motor racing and on urban streets to slow the pace of traffic. Said they were going to build some in the next street, but no chance of that now in the face of massive public spending cuts.
