Taylor earlier defied the tribunal, refusing to attend the start of hearings June 4, and then June 25, firing his lawyer, and calling into question the court's impartiality. Last week a judge ordered the court ensure Taylor had another four people on his defense team to ensure a fair trial.
The UN Security Council previously urged the UN secretary general to renew investigations into reports that Taylor may still have access to considerable wealth.
In a unanimous resolution, the council asked Ban Ki-moon for a new panel of up to three experts to carry out a follow-up assessment mission to Liberia and neighboring countries to determine the effectiveness and impact of the measures introduced against Taylor and others.
Taylor, who fought as a warlord in the Liberian civil war in the early 1990s before becoming president, is being tried in The Hague for war crimes in Sierra Leone, including mass murder, rape, mutilation, and recruiting child soldiers during the coastal African nation's 1991-2002 civil war.
He has demanded that the court pay his legal expenses, pleading poverty, but a five-member expert panel earlier reported to the UN that there are "credible allegations" that Taylor has substantial investments in Nigeria that have not been frozen.
A Security Council resolution in 2004 ordered all governments to freeze the assets of Taylor, 59, and his immediate family, and barred them from using "misappropriated funds and property" to obstruct the restoration of peace and stability in the region.
The former African leader, who was deposed in 2003 under a peace deal ending the Liberian Civil War, is implicated in the killing of up to 200,000 civilians in Sierra Leone, notably through his support for a campaign of terror unleashed by a brutal local guerilla group, the Revolutionary United Front.
Taylor fled to Nigeria after being ousted, but was arrested on an international warrant and deported to Sierra Leone in March 2006. He has been held at a detention center in The Hague since last June.
The former warlord, who has pleaded not guilty to all charges, said in a letter that he doubted the Special Court for Sierra Leone, set up in the capital Freetown in 2002, could ensure a fair trial for him. Amid security concerns, the trial was moved to the International Criminal Court in The Hague last year, but hearings are still being conducted under the auspices of the Freetown court.
