Joseph –
I will B”N do so.
If the rav I ask gives his OK, I will also mention his name.
I am a terrible procrastinator, so it may not be that quick, but since at least one person is now waiting on this the incentive to get up and ask exists.
The reason I will ask the rav for his permission to quote something in his name is that in the past I asked Rav Belsky shlita for a psak and then asked if he could be quoted to others he gave the OK, but when I asked a Rosh Yeshiva about kashering a microwave for Pesach, he said technically it was OK, but it shouldn’t be done, and when I was leaving yeshiva to enter the business world I asked my Rosh Yeshiva about shaking hands with women and he said “it is muttar, but you shouldn’t” – I took the last two statements as applying for me personally, and not for public attribution.
One note about dina dimalchusa – I was told that it may apply even where it contradicts halacha, such as capital punishment in the USA, since it has a malchus shel chessed and the punishment is applied fairly to all people. This is NOT a psak I was given but it was mentioned during learning by someone whose learning I respect.
