Possessive ambiguity

"Senate Bill 250 limiting free-speech rights in Ohio is unneeded and pernicious", cleveland.com 1222018 [emphasis added]:

A pending Ohio bill […] seeks to turn the state's misdemeanor criminal trespass law into a felony if it involves knowingly entering a "critical infrastructure" site. […]

The American Civil Liberties Union of Ohio's Gary Daniels told the Judiciary Committee that SB 250 and its related bills across the country "are meant to end and severely limit criticism, exposure of … corporate wrongdoing, or anything that merely inconveniences" the builders or operators of "critical" infrastructure.

The link is  from Patrick Nevins, who needed a couple of re-readings to figure out that they meant to attribute the quotation to Gary Daniels from the ACLU of Ohio, rather than to an ACLU somehow belonging to Gary Daniels of Ohio.

It's easy to find examples of both ways to parse sequences of the form

ProperNoun of ProperNoun 's ProperNoun

[X of [Y's Z]]: Al Hodgson of California's Lawrence Berkeley Laboratory [[X of Y]'s Z]: the University of California's Berkeley campus

But in the [[X of Y]'s Z] type, [X of Y] is usually a familiar phrase easily taken as a unit, e.g.

the University of Pennsylvania's Wharton School the University of Denver's Daniels College of Business The University of Virginia's Cavalier Daily

For the writers of the cited editorial, "the American Civil Liberties Union of Ohio" apparently coheres strongly enough as a unit to establish itself as the possessor in the 's construction. But for readers like Patrick, the phrase tips the other way.

The waning animacy constraint on apostrophe-s possessives may also be a factor. See:

"A correlate of animacy", 9/27/2008 "The genitive of lifeless things", 10/11/2009 "Mechanisms for gradual language change", 2/9/2014 "*The haystack's painting", 12/9/2015

Overall, it's clear that avoiding such ambiguities has not been high on the list of factors influencing the (biological or cultural) evolution of language.
