No lar a lot of the times the (rightful) assumption on client's part is that you know the law. So, if you know, then u research for what? and bill me some more?

Unless it's a damn rare or complex point of law or procedure. I mean nobody expect u to memorise ROC, but at least be familiar enough above and beyond your soc-defence-reply. Some people I talk to only know these and attend PTC sia, if I were sophisticated/savvy client confirm won't use them what. Then whole career only MC suit tier debt collector.

So a bit of chicken and egg lah.
