Trials of paladins are not typically controversial affairs. Typically speaking, the cases are open and shut, and the most common alternatives are rarely interested in making a serious fight of it. When Heaven and Nirvana disagree on a sorting and the opinion of the petitioner is not decisive, they usually hash it out ahead of time in a discussion that usually converges on agreeing to support whichever position has the highest probability of resulting in a Good ruling they can manage, and in the rare occasions this is not the case the disagreement is typically handled by junior lawyers who need practice arguing cases with low stakes and the big hitters saved for trials that can save a soul. Likewise for the most part for Heaven versus Axis, and in any case there are not altogether that many Paladins who reliably manage Law but not Good. Sometimes, of course, there are confounding factors due to the god worshipped - in ages past a Lawful Good paladin of Aroden might aim for His realm in Axis, or agents of Sarenrae lay claim to a particularly aligned Paladin indifferent between Nirvana and Heaven - but these are more the exceptions to the rule and rarely exciting case law.
