The intent, presumably, was that Protection from Law works exactly like Protection from Evil, except replacing all instances of "evil" with "lawful" and all instances of "good" with "chaotic".
That's not what they wrote, though.
Protection from Evil: Third, the spell prevents bodily contact by summoned creatures. This causes the natural weapon attacks of such creatures to fail and the creatures to recoil if such attacks require touching the warded creature. Good summoned creatures are immune to this effect.
Protection from Good: This spell functions like protection from evil, except that the deflection and resistance bonuses apply to attacks from good creatures, and good summoned creatures cannot touch the subject.
Protection from Law: This spell functions like protection from evil, except that the deflection and resistance bonuses apply to attacks from lawful creatures, and lawful summoned creatures cannot touch the subject.
Protection from Chaos: This spell functions like protection from evil, except that the deflection and resistance bonuses apply to attacks from chaotic creatures, and chaotic summoned creatures cannot touch the subject.

So for Protection from Evil: All summoned creatures are warded, but Good creatures are immune to this effect.
Expected result: All but Good are warded.
Actual result: All but Good are warded.
For Protection from Good: As Protection from Evil (All summoned creatures are warded, but Good creatures are immune to this effect), except that Good summoned creatures cannot touch the subject.
Expected result: All but Evil are warded.
Actual result: All are warded.
For Protection from Law: As Protection from Evil (All summoned creatures are warded, but Good creatures are immune to this effect), except that Lawful summoned creatures cannot touch the subject.
Expected result: All but Chaotic are warded.
Actual result: All but Good are warded.
For Protection from Chaos: As Protection from Evil (All summoned creatures are warded, but Good creatures are immune to this effect), except that Chaotic summoned creatures cannot touch the subject.
Expected result: All but Lawful are warded.
Actual result: All but Good are warded.

Badly written. Protection from Good is more powerful than the other three spells, and PfL and PfC don't act as expected.
