A South African court has refused permission for President Jacob Zuma and prosecutors to appeal against its ruling that he should face corruption charges over a 1999 arms deal worth billions of dollars.
There were "no merits" in the argument requesting an appeal, it ruled.
In April, the court said a 2009 decision to drop the 783 charges against Mr Zuma was irrational.
He has always denied taking bribes over the arms deal.
National director of public prosecutions Shaun Abrahams had asked the court for permission to appeal against the earlier ruling, saying prosecutors should be able to exercise discretion over whether an investigation should continue.
Rejecting the request, High Court Judge Aubrey Ledwaba said: "We seriously considered whether the appeal would have reasonable prospects of success and came to the conclusion that there are no merits in the arguments."

The president can still take the case to the Supreme Court of Appeal but it is difficult to see it overturning the unanimous ruling of the High Court, our correspondent says.
Mr Zuma's final option would be to ask the Constitutional Court to throw out the case.
Controversial arms deal: What you need to know
- 1999: largest-ever post-apartheid arms deal announced, with contracts totalling 30bn rand ($5bn; £2.5bn) to modernise national defence force
- Deal involved companies from Germany, Italy, Sweden, the UK, France and South Africa
- Allegations of bribery over deal dogged governments of President Jacob Zuma and predecessor Thabo Mbeki
- Mr Zuma's former financial adviser Schabir Shaik convicted in 2005 for corruption over deal. Found guilty of trying to solicit bribe from Thint, local subsidiary of French arms firm Thales, on behalf of Mr Zuma - then deputy president. Released on parole on health grounds after serving just over two years
- Another official, Tony Yengeni, chairman of parliament's defence committee at time of deal and ANC chief whip, convicted of fraud in 2003. Also freed on parole after serving five months of four-year sentence
- April 2016: commission of inquiry into deal found no further evidence of corruption or fraud
In a separate case in March, the Constitutional Court said Mr Zuma breached his oath of office by failing to repay government money used to upgrade his private residence with a swimming pool, amphitheatre, chicken run and cattle enclosure.
It backed an earlier ruling by an anti-corruption body that said $23m (£15m) of public money had been improperly spent on Mr Zuma's rural home in Nkandla in KwaZulu-Natal province. www.bbc.com
