There's a bit of a backstory to this. Without boring you too much with the details in 2006 a London based oil trading firm, Trafigura, (allegedly, in the way the Pope is allegedly Catholic) dumped tonnes of chemical waste around Abidjan in Ivory Coast. In the weeks following tens of thousands of residents began complain of similar symptoms, including diarrhoea, sickness and breathing difficulties.
Group action was taken against the company in Feburary 2007 on behalf of tens of thousands of Ivorians. Trafigura denied the allegations, but paid the Ivorian Government £100 million to clean up the waste. The company blames a local contractor, the heads of which are jailed.
In May 2009 Newsnight reported on documents detailing the cargo, including its hazardous nature. Trafigura responds by suing the BBC for libel.
That brings us up to last month, when the Guardian uncovered Trafigura's internal emails, indicating staff were aware that disposal of the waste could be hazardous. You can see these documents
here. In the same week the company agrees to pay compensation of £1000 to all 30,000 people injured by their dumping.
So that is the situation. Two days ago, though, I got to work and there was a lot of rumour about the going ons of Trafigura and their legal firm, Carter-Ruck. The media offered no enlightenment, but we soon found out what was going on.
The Guardian ran a front page story on how it had been served a gag order by Carter-Ruck on the matter of a Parliamentary Question that had been filed for the next week. They couldn't reveal when the question was to be asked, who was to ask it or what it was about. They were set to appeal the gag in the High Court the next day.
Amazingly what the Guardian had been prevented from reporting was an oral question tabled by the Labour MP Paul Farrelly to Secretary of State for Justice, Jack Straw;
"To ask the Secretary of State for Justice what assessment he has made of the effectiveness of legislation to protect (a) whistleblowers and (b) press freedom following the injunctions obtained in the High Court by (i) Barclays and Freshfields solicitors on 19 March 2009 on the publication of internal Barclays reports documenting alleged tax avoidance schemes and (ii) Trafigura and Carter-Ruck solicitors on 11 September 2009 on the publication of the Minton report on the alleged dumping of toxic waste in the Ivory Coast, commissioned by Trafigura."
Now, I'm sure you realise why this matter is entirely appalling. Not only is it an outright attempt of an unethical, practically criminal company to cover its tracks, but it is a shocking contravention of Parliamentary priviledge and the freedom of the press. Never before has the media been stopped reporting to the people of Britain the events happening in their own Parliament in open session.
Fortunately, however, the little information that the Guardian was allowed to print was enough for people on Twitter to discover the Parliamentary Question that the gag order referred to and in a matter of hours it must have become the most read Parliamentary Question in years. This is a manual in how to

up PR.
In the following 16 hours, through Twitter, word was spread, a "silent" protest was organised for Thursday 15th October outside Carter-Ruck's offices and people like Stephen Fry, Graham Lineham and Charlie Brooker were spreading the story among their hundreds of thousands of followers.
Yesterday, an hour before the Guardian was set to appear in the High Court, Carter-Ruck dropped the gagging order, and the scandal became common knowledge.
It may not be the Iranian protests, but its amazing how Twitter is showing such value so early in its lifetime. I believe its probably the most significant development for democracy for decades.
