Suzette Kelo certainly did have due process. We may not have liked the outome, but you can't say it wasn't due process. It's not like the state just came in the middle of the night and threw her off her land, like they do in Zimbabwe.
BTW and FYI, Suzette Kelo and the other defendants still own their property, and it looks like public pressure is forcing the city of New London to abandon its plans to take their properties.
No, there was not due process. An unelected body (New London Development Commission) decided to take her property by eminent domain. This was not conducted in a court of law with strict procedures for finding evidence, but by a process of administrative hearings.
And the "public pressure" you mention is not due process, either. Whether she keeps her property or not, there was not due process.
