Each Ranger gets one Seal, a small metal piece in the shape of a stylized eagle. You give it to a likely recruit and they use it as their sign of free passage to get to the Sacred Hills and apply to the Oracles for membership in the Rangers. So long as they actually show, you get the Seal back when you next visit the Sacred Hills, regardless of whether they were accepted or not (there's probably a machine-carved unique ID number of the back of each one). If they don't show, well... you may want to go looking for them.
Rangers who have produced successful recruits in the past may be given an extra Seal or have their current one replaced if they lose it. Others tend to be stuck until they recover it.
A formal inquiry requires all of the Rangers in a team to vote on what to do... generally a "guilty/not-guilty" vote to determine whether or not an accused Beast should be killed or otherwise punished. The common verdicts are Innocent (no punishment), Investigation (insufficient data, we'll look into it further), Reprimand (public exposure and an oath to not re-offend, reserved for minor offenses), Slashing (like a Reprimand, but much more painful), Mark (the cutting off of appropriate bits, such as castration for rape or inflicting injuries on them similar to what they did to their victim... marked individuals often become outcasts) and Execution... Markings sometimes require a second vote, as to what sort of maiming should occur. Since Beasts are not supposed to harm other Beasts, Execution is supposed to be reserved for the worst of offenses, but sometimes it's used punitively.
A Caretaker can always override the votes of any number of Rangers. If a Caretaker is present, the Rangers usually don't even vote unless the Caretaker tells them to... Caretakers hardly ever ask anyone else's opinion, but sometimes will say that they lack sufficient information or are too busy and delegate the decision to the Rangers.
In order for there to be a proper vote, Rangers usually travel in groups of at least 3.
If there is an even number of Rangers, the most junior Ranger doesn't get a vote.
Technically, you're required to pick a verdict... Rangers are never supposed to say "I don't know", but they sometimes do. If you aren't sure, your verdict is supposed to be "Investigation" and the investigation continues until you are sure. But sometimes events or time pressure won't permit that and then they have to make the hard choices.
Caretakers and upper rank Rangers tend to seriously frown on indecisive Rangers... displaying clear leadership and settling an issue in a way that the locals will accept is more important than getting it right.
Knowingly attacking a Ranger, attempting to hinder their work, or just plain deliberately ignoring their orders is considered to place a Beast outside of the Law and makes them into a renegade/ravener immediately. The exception is Beasts possessed by Shadows, who thus are no longer in control of their actions.
If the vote isn't unanimous, you redo it up to 3 times. If it's still not unanimous, go with the majority. I'm thinking like the Cirinists in Cerebus here. "Execution." "Execution." "Questioning." [pause] "Execution." "Execution." "Questioning." [pause] "Execution". "Questioning!" "...Questioning."
Rangers hate giving Reprimands. The general consensus is that if the offense was minor enough to merit just a Reprimand, then the locals should handle it themselves. Verdicts of Innocent are more common, especially since they don't require a public gathering and further effort on the Rangers' part.
Actually, Reprimand might not even be one... it's just a warning that you choose to issue (or not) when you give an Innocent verdict.
