Speaking only with respect to the US:

I am aware of no such law.

However, I am aware of a law that makes it unlawful for a bunch of
large providers who already have large blocks of space to collude to
prevent new entrants into the market by refusing to carry their routes.

If the guy with the /28 he can't route alleges that that's what's
happening, there are lots of arguments on the other side the ISPs with
the filters could make.  They've been filtering at /24 for a lot longer
than it started to seriosuly harm new entrants into the market ...
there was never any formal agreement to filter at /24; it just happened
(but everyone ended up filtering at /24 ... that wasn't just
coincidence) ...  there are real technical reasons for limiting FIB
size ... and so on.  I don't know who would win the anti-trust lawsuit,
but I wouldn't consider it a slam dunk for the ISPs doing the
filtering.

I don't expect there to actually be such a lawsuit.  Among other
things, buying a /24 will likely be cheaper than litigating this, so
the only way it gets to trial is an organization litigating on
principle.  And, as I said, I'm not convinced the filtering providers
lose if there is one.  But anytime the big guys collectively have a
policy that keeps out the new entrants, there's anti-trust exposure.
