The issue of gelatine and the view of R’ Chaim Ozer is well-known and as old as the hills. Sure, the Oilom Goilom think that someone has suddenly leaped to R’ Chaim Ozer’s defence and set him back up on the pedestal of decisor for all. Well, R’ Chaim Ozer was and remains so! On the issue of Gelatine from Cows (not Pigs) however R’ Chaim Ozer’s Psak was not accepted.
So what next? You can expect Meir Rabi to scour every nash in order to ascertain that they definitely don’t use pig gelatine and then make a splash that the delicacy is now suddenly kosher after all.
Well, the facts are that all major world-respected Kashrus authorities didn’t and don’t accept R’ Chaim Ozer’s Psak. Those of you who want to follow Meir Rabi and his company (they curiously claim a”community service”, heck, it’s a private profit making business making money out of declaring things kosher) go right ahead.
For the rest of us, I suggest you read Rabbi Eli Gersten, here.

As far as I know it’s only in the USA that the majority don’t accept R Chaim Ozer’s (and Dayan Abramsky’s, and many other poskim’s) position. In EY the Rabbanut (non-mehadrin) does accept it, and I believe so did most non-USA hechsherim before the recent trend to internationalise the US standards.

As far as I know, the Psak wasn’t accepted during R’ Chaim Ozer’s reign. It was rejected by his contemporaries, and had nothing to do with standardisation or location.
There have always been Rabonim who disagreed, but the vast majority didn’t and do not accept the Psak. Perhaps we should standardise on the Chazon Ish’s better for Chalav
Hacompanies?
