Daniel Ettedgui asks:
A 10 amot breach in one wall of a chatzer invalidates it for carrying. A sukkah is completely valid with only 2 1/2 walls! How could a d'rabbanan law be more stringent than a d'orayta law?
Daniel Ettedgui, Boca Raton, USA
The Kollel replies:
This law applies to Sukah as well, see Shulchan Aruch Orach Chaim 630:5.
All the best,
Yaakov Montrose
