I feel like most of the cases with the caption "Union Pacific R.R. v. Superior Court" are from an earlier century -- say, the 1800s. That's definitely when railroads were most heavily involved in litigation, and that's where most of the railroad cases we read in law school come from. (Maybe early 1900s as well.)
But this one is definitely a product of a more modern -- post-automobile -- era. As well as one with probably even greater significance to ordinary landowners than to any particular railroad.
The question presented is whether a landowner who owns property that abuts a public street is liable when cars on that street crash, veer off the street, and hit a tree located on the landowner's property. That's what happened here, and there's little doubt that hitting the tree substantially increased the resulting injuries to the driver.
Are you liable for letting a tree grow on your property when it might injure someone who veers off the street (perhaps, as here, allegedly through no fault of their own)?
I think I'm fairly on board for that result. The issue is whether there's a duty under those circumstances; that in turn involves balancing a ton of different factors. On the whole, the Court of Appeal's opinion seems right to me. Yes, we could -- if we wanted to -- impose a duty on people with respect to trees on their property, and, yes, that might decrease (for some crashes) the resulting injuries. But I'm not sure it's worth it, and the resulting rule might well go too far. For one thing, personally, I like trees; they're good for the environment. (Plus they're pretty.) For another thing, if we impose a duty, I'm worried the resulting rule would go too far. Most of us -- or at least most landowners -- own property that abuts a public street. Most of us also have things that might increase injuries to someone who veered off that street and came onto out land; a tree, a concrete wall, a parked vehicle, or the like. It's just too much, I think, to hold that we all have a duty to minimize those common (but admittedly potentially injury-causing) obstructions. When applying the relevant balancing test, I tend to agree that imposing a general duty probably just goes too far for me.
That said, Justice Snauffer somewhat lost me -- at least in terms of persuasive value -- at around page 28 of the opinion, and continuing to around page 32. There, Justice Snauffer articulated at length his view that imposing a duty in such settings might well constitute an unconstitutional "taking" of private property without just compensation.
I don't agree with that. There are lots of regulations that restrict what you can do with your land. Some of them (e.g., zoning and environmental rules) are infinitely more onerous than any duty that even possibly be at issue in the present case and yet are entirely permissible. Others are directly relevant to public safety and entirely permissible notwithstanding the view that you're allowed to do on your own property whatever you want. You may well, for example, want to set a spring gun on your property to deter or incapacitate would-be criminals. Tough luck. We can 100% permissibly prohibit that, and it's not an impermissible taking. So too here.
If we rationally concluded that huge trees right near a fast-speeding highway were injurious to public health, well, sorry, then you can't grow them. Ditto, by the way, if you want to put a half-dozen spears on your property pointed right towards the road. Yep, it's your land. Nope, you can't do that, and any claim that such a prohibition constitutes an illegal "taking" should (and would) fail.
So I'm on board for the result, but part of the underlying analysis actually pushed me in the other direction, rather than ostensibly supporting (as was the point) the opinion's conclusion.
Maybe I'd go the other way, in this particular case, if there was zero reason for the tree being there, or if it was literally right next to the road (as opposed to 20 feet from it) and the road was a super-fast and oft-crashed freeway. Maybe. But, here, I think the Court of Appeal gets the result right.
Even if its analysis, in places, might go a little too far.
