Gelatine derived from non-halaal sources

Q: What is the Shariah ruling regarding gelatine? Most of the halaal certifying bodies here are of the opinion that gelatine derived from non-halaal sources is halaal. They aver that the gelatine derived from non-halaal sources undergoes a "metamorphisis" and therefore is halaal. But the matter is indestructible and surely their contentions cannot be correct? However, it eludes logical comprehension that apparently our Ulama has yet to challenge the halaal certifying bodies concerned in regard to the issue and the halaal certifying bodies remain unchallenged. But what is your take on the matter?

Making wudhu with compression stockings

Q: An old lady has been advised by a doctor to wear compression stockings on her legs for circulation. She doesn't have any wounds etc. on her legs. The stockings are from her knees and only the toes are open.

The stockings are very tight and she requires someone to put it on and remove it for her. Is it permissible for her to make masah over the stockings and only wash the toes for wudhu?
