My instructor had me print FCOM 1.27.30 p2 FLIGHT CONTROLS LAW RECONFIGURATION schematic. It is not an easy read especially because subsequent text pages use different names for the various regimes.

The way I read it is that in ALT LAW, you can never have all protections. Some are lost. ALT LAW - REDUCED PROT (schematics) = ALT LAW (text)
  • load factor - available
  • pitch attitude - gone
  • low & high speed stability - available
  • bank - gone

ALT LAW - NO PROTECTION (schematics) = ALT LAW WITHOUT REDUCED PROTECTIONS (text) this in fact is understood as ALT LAW with even less protections than in REDUCED mode
  • load factor - available
  • all others - gone

In which case your question may be answered by the left most branch of the schematics
  1. double ADR failure (2nd not self detected and/or speed/mach disagree)
  2. triple ADR failure
  3. duble SFCC slat channel fault
  4. G+B HYD lost
this would be called ALT LAW with NO PROTECTIONS albeit, obviously, the g-load prot is still available.
