I'm not sure Pen, I honestly don't know and not very knowledgeable on the subject. Could it have been to do with the 3 year rule, where, only after 3 years of separation/waiting period, a divorce could be filed ? Did they want to get rid of the 3 year rule ?
Perhaps the Society's concerns were being aired because government were in the process of drawing up the Matrimonial Clauses Act of 1950. If so, I'm finding it hard to say if they'd have been for or against it!
The other thing that I was intrigued about, was the Organising Committee was based in Kingstanding. Wonder if it reflected on the rise in breakdown of marriage and/or the effects of post-war strains on marriage in the area. (Although it wouldn't, of course, have been exclusive to the area, but there must have been a catalyst for a committee to emerge from there).
