Is it possible for a Jew who is in mourning (an ovel) to attend a wedding on Zoom?
My intial thought process was why not? If one cannot be משתתף (join) with a virtual minyan (quorum of 10 men) as all 10 need to be in one place (see OC 55:13) - perhaps in a similar vein an online wedding is the same as it is like one is not truly part of the proceedings, and worse case scenario if there is music etc. one can mute.
But then I realised that with a minyan the issue is principally about being there whilst with a wedding it is not, it is first and foremost the Simcha (happiness) - Indeed, the Shulchan Aruch expressly states that an ovel has to abstain from any type of joyous occasion:
אבל אסור בכל מיני שמחה (YD 391)
Thus if joining with a zoom wedding will generate Simcha - is he allowed to participate?
I am aware that the are differing levels of mourning depending on how much time has elapsed - i.e. initial shiva (first seven days), shloshim (first 30 days) and then the remaining year which may affect the answer.
