Aldershot News & Mail trainee Elena Cresci, left, applied to have the Section 39 order overturned at Guildford Crown Court.
The order related to a case involving a man who was accused of assaulting a baby.
Elena, 23, challenged the order on the grounds that the child was too young to be harmed by any publicity stemming from the case.
The crown court judge considered the challenge for 24 hours before deciding that he should revoke the order.
It is the latest in a series fo cases where reporters have successfully overturned S39 orders wrongly imposed in respect of babies.
Said Elena: “It was a daunting experience at first, but I was glad to get the order overturned so we could accurately report the case.
“I definitely wouldn’t have been able to do it without support from the team or the media law training I’d received at Cardiff University.”
News editor Richard Pain added: “Elena immediately recognised that it would be impossible to provide a fair and accurate account of the trial if the order remained in place.
“She had only been in the job for less than four weeks but was bold and showed no hesitation in wanting to put her argument before a crown court.”
In a similar case last year, Surrey Advertiser trainee Stephanie Jones-Berry challenged a Section 39 Order covering a baby girl who suffered permanent brain damage at five-weeks-old at the hands of her parents.
Stephanie also argued successfully that the child was too young to be affected by adverse publicity.
