I read this book when I was a teenager, nearly 50 years ago, and just finished re-reading it. It holds up surprisingly well for a half-century-old work of speculative fiction. Sure, the technology is dated, and you have to mentally multiply all dollar figures by a factor of 20, but as social commentary it's still readable and even engrossing. P&K's portrayal of a decaying, corporate-controlled America is well crafted, with vivid descriptions and dialog. Their grasp of economics is spotty, and Pohl's far-leftist sympathies are all too evident (he was a Communist in his younger days) but the narrative moves along briskly, and the characters are vivid and memorable. I hesitate to give this five stars; it's really more like a 4.5 star entry, but why quibble. GLADIATOR AT LAW is among the classics of mid-century SF.
