I do not have a clue about SJR7. The most I can tell you it has to do with defining marriage. And some language in the Indiana Constitution will need to be changed to accommodate same sex marriage. And next week Indiana house will hold a hearing on the proposed changes.
Indiana Law Blog discusses SJR7 in detail.
But nobody discusses it more than Advance Indiana, all over his blogspot.
Get informed by reading the exchange of information on the two sites and don't forget to read the actual bill. This is one hot topic.
