A teenager who claims she was unlawfully segregated inside Canberra's youth justice centre for almost two months has accused ACT authorities of breaching her human rights.

The young woman — who is serving a three-year sentence for aggravated robberies and burglary committed when she was a minor — also claimed that during that time her personal items, including Indigenous artwork and cultural reading material, were unfairly confiscated by Bimberi staff.

Her allegations are the latest to emerge against the youth detention facility.

Last month an ACT Human Rights Commission report revealed a young person in handcuffs was punched by a staff member, in retaliation for being attacked by three detainees during a violent assault.

Artwork, newspapers removed because they 'undermined security'

The woman's lawyer, Tom Taylor, filed papers in the ACT Supreme Court seeking a declaration that her rights had been breached when she was wrongly separated from other detainees and when she was restricted from maintaining and developing her cultural heritage.

Court documents said the woman had been in custody since March last year and permanently locked up in Bimberi since September.

In October, she was separated from the general population and put in the Coree Unit — used for both incoming prisoners and for the segregation or management of detainees — for almost two months.

During this time, she had a number of items removed from her room, including her artwork and Koori Mail newspapers.

According to the lawsuit, Community Services Directorate youth executive director Helen Pappas confirmed in March that the detainee had not been given a written segregation order, as is required by law.

Ms Pappas is also alleged to have claimed that the Indigenous artwork and newspapers were removed because "they were excessive" and "undermined safety and security at Bimberi".

But the woman's lawsuit alleged the confiscation was "incompatible with the plaintiff's right to maintain and develop her cultural heritage" under the Human Rights Act.

The case also alleged the decision to move the inmate to the Coree Unit and away from the general population had actually put her in segregation.

"The defendant has acted in a way that is incompatible with a human right through segregating the plaintiff unlawfully within the Bimberi Youth Justice Centre, by restricting or denying the plaintiff's opportunity to go into or be in particular parts of Bimberi, or to associate with other young people in Bimberi," documents said.

"No segregation direction or written notice of the segregation direction was ever given to the plaintiff... against the Children and Young People (Segregation) Policy and Procedures."

In a statement to the ABC, the Community Services Directorate maintained that Bimberi was "a Human Rights compliant facility, where young people are aware of their rights and staff are trained and supported to uphold the rights of each individual young person".

While the directorate would not comment on specific cases, it said all young people had direct access to "official visitors", including an Aboriginal and Torres Strait Islander official, to raise any concerns.

The case is expected to first appear in court later this week.

Review discounts staff having 'a disregard to human rights'

Bimberi was opened in 2008 as a replacement for the scandal-plagued Quamby Youth Detention Centre, but has also attracted criticism.

The ACT Human Rights Commission last month published its long-awaited review into allegations and concerns about the treatment of detainees at Bimberi Youth Justice Centre from 2014 to 2017.

The allegations included claims of inappropriate and excessive use of force, racism, privacy breaches and staff encouraging fights between young people.

The report substantiated a number of claims but found Bimberi did not have an entrenched culture of violence or disregard to the human rights of detainees.

Among the report's 15 recommendations were the upgrading of CCTV and training staff in the safest techniques for use of force.
