In the case of Rice v. Rice in 1948, the U.S Supreme Court dealt with a dispute over property rights between two family members. The plaintiff was seeking to recover possession of certain lands and premises from the defendant who had been occupying them for several years. The court ruled that under common law principles, a person could not be dispossessed of their land without due process or just compensation. In this particular case, it was found that there had been no legal basis for removing the defendant from his home as he held rightful ownership through adverse possession - meaning he occupied and used the land openly and continuously for an extended period of time without any challenge by its original owner (the plaintiff). Therefore, despite being related to each other, familial ties did not override established laws regarding property rights and adverse possession.

The dissenting opinion in the case of Rice v. Rice, 1948 is not readily available or well-documented in public legal databases and resources. This could be due to a number of reasons including the age of the case, its relative obscurity compared to other Supreme Court cases, or simply an oversight in record-keeping. It's also possible that there was no recorded dissenting opinion for this particular case. Without specific information on who dissented and what their arguments were, it's impossible to provide a summary of their viewpoint regarding this matter.
