Check this out: the International Right of Way Association’s Real Estate Law Committee produces twice-a-year reports “which contain summaries of eminent domain decisions and legislation within the United States.” (This is the “international” right of way association, so that last qualifier is important.)
And what is really nice is that they make the report available.
We’re posting it here because we’re one of the co-authors. The laboring oars on this are really Brad Kuhn and Jullian Friess Leivas (both from the Nossaman firm), but they were kind enough to ask me for some input.
Brad and Jillian wrote up more at the California Eminent Domain Report.
The report is short, and doesn’t have a lot of fluff. Just what you wanted.
