The situation in Justice is totally different than The Apple for example. They are already on the planet that is known to them...
Wrong.
I seem to recall some lines where the crew state there has been study of the planet, so I assumed there may have been contact...if not this is technically a PD violation. However I do agree with speech made by Picard at the end, and it has nothing to do with expansionism or treaty ports. Yes, definitely a story mistake here...Captain's log, stardate 41255.6. After delivering a party of Earth colonists to the Strnad solar system, we have discovered another Class M planet in the adjoining Rubicun star system. We are now in orbit there, having determined it to be inhabited as well as unusually lovely. My first officer has taken an away team down to make contact and they are in the process of returning to the ship.
In the Apple, Kirk, investigates readings and is clearly not wanted, and unilaterally make a decision effecting the whole planet!
It seems likely that Vaal or its creators had some sort of biosphere experiment going, or there was some plan Kirk could not be aware of, possibly even meant to save or advance the natives. If that's the case Kirk immediately causes contamination and threatens the society...and of course this comes to pass. I don't condone "shooting first" but VCaal may have seen it the other way around...I love how you continually leave out the fact that Vaal attacked first and refused to allow Kirk and his landing party to leave.
Add to this, the disturbing fact they are thinking of taking OVER the planet despite the existence of natives on IT!!!KIRK: Well, the last scout ship reported some pretty strange sensor readings.Starfleet wants it investigated and the inhabitants contacted. We do what we're told.
SPOCK: The soil here is remarkably rich and fertile, Captain. Husbandry would be quite efficacious.
KIRK: Are you sure about that?
SPOCK: Oh, quite sure. Readings indicate the entire planet is covered with growth like this. Curious, even at the poles there's very little variation in temperature which maintains a planet-wide average of seventy six degrees
So again, what are the motives here? Research? Not like with the Edo.
