Responsa for Bava Kamma 173:2
תניא אידך ר' יהודה אומר סומא אין לו בושת וכן היה רבי יהודה פוטרו מכל מצות האמורות בתורה אמר רב שישא בריה דרב אידי מאי טעמא דר' יהודה אמר קרא (דברים ו, א) ואלה המצות החקים והמשפטים כל שישנו במשפטים ישנו במצות וחקים וכל שאינו במשפטים אינו במצות וחקים
who is not subject to the law of the 'smiter' and the 'avenger of blood' is not subject to judgments. Another [Baraitha] taught: R. Judah.says: 'A blind person is not subject to [the law of] Degradation. So also did R. Judah exempt him from all commandments stated in the Torah.' R. Shisha the son of R. Idi said: The reason of R. Judah was because Scripture says: Now this is the commandment, the statutes and the ordinances;<span class="x" onmousemove="('comment',' Deut. VI, 2. ');"><sup>3</sup></span>
Teshuvot Maharam
A. Authorities differ regarding the rights of a husband over his wife's dowry. Some authorities decide that a husband has the rights of a buyer [who is not responsible for the seller's debts] while others hold that his rights are those of an heir [who is liable for the debts of his benefactor]. Since we can not choose between these conflicting opinions, we allow the money to remain in the hands of the present possessor. And since L has no money and will have no money till she be widowed or divorced, there is no sense in exacting an oath from her. We give B a written verdict, however, to the effect that in case L be widowed or divorced she then must take an oath denying B's claim or pay that debt.
