Phillip,
I agree this sounds fishy.
Not sure about Mozambique changing laws after hunts have been sold and right before the season, but Tanzania has done this, I believe four times since 2006. Some decisions are made the end of June. Changes are made and the season starts July 1.
1. Around 2006 they changed government fees through the roof. Outfitters had to eat the cost or pass it on. Went over poorly.
2. Apx. 3 years ago while clients were in the air, they raised the hunting age to 16(I believe). Kids were in the air with their fathers only to find out when they landed that they couldn't hunt. (There may have been something worked out on this but the government didn't care)
3. Last year 18% VAT was added before the season started. That's a pretty big hickey for most to absorb.
4. Can't remember the fourth at the moment. Maybe someone can help me.
Not saying this is a legitimate post, or that Mozambique would do this, but Tanzania certainly has and probably will again.
Don't rely much on an African bureaucrat.
