Thailand's billionaire Shinawatra family are undoubtedly political survivors.
Over two decades, they have survived two military coups and three court rulings that collectively toppled three of their governments and five prime ministers.
But the imminent findings of multiple court cases could reshape the family dynasty and the political landscape of Thailand.
Here's what we know about the cases faced by suspended Thai Prime Minister Paetongtarn Shinawatra and her influential but controversial father, Thaksin Shinawatra.
What is Paetongtarn Shinawatra accused of?
Thailand's suspended prime minister is accused of failing in her duties by not standing up for the country properly.
The central issue is what she said in a leaked phone call with former Cambodian leader Hun Sen.
The call focused on the then-brewing border dispute between the neighbouring countries.
In the call, Ms Shinawatra addressed Hun Sen as "uncle" and referred to a Thai military commander as her "opponent", sparking a furious reaction in Thailand.
Conservative politicians accused her of kowtowing to Cambodia and undermining Thailand's military.
The backlash was almost immediate, with the main party in the country's ruling coalition walking out in protest over her conduct on the call — a move that almost collapsed her government.
A group of senators filed a petition with the Constitutional Court arguing she should be removed from office for breaching constitutional provisions that require "evident integrity" and "ethical standards" among ministers.
She has always denied any wrongdoing.
As well as sparking a domestic political crisis, the phone call plunged relations between Thailand and Cambodia to new lows.
The border row later erupted into the deadliest military clash between the two countries in decades, with more than 40 people killed and 300,000 forced to flee their homes along the border.
On Thursday, her 39th birthday, she testified in front of Thailand's Constitutional Court for about an hour and a half.
A court ruling has banned any reporting of what she said.
She was flanked by a senior advisor and waved at a crowd of supporters as she left.
The court will rule next Friday on whether she should be permanently removed from office.
She has received support from Thailand's acting prime minister, Phumtham Wechayachai.
"I believe there was nothing that affected the country's security, and I trust her intention to keep Thailand out of conflict," he told reporters.
Legal advisor and former special counsel to the deputy prime minister of Thailand, Verapat Pariyawong, told ABC's The World the case was a "very murky area between law and politics".
"If the prime minister shot someone, or committed a crime, or committed bribery, then it's quite a straightforward question of facts and law," Mr Pariyawong said.
"But we are talking about a prime minister in a private call with another former leader of a neighbouring country, trying to secure a peace deal, so to say. So whether one could judge that her attempt to prevent bloodshed, to prevent military escalation, was done in good faith is, in my view, a political question."
He said it remained to be seen how the court would address the issue.
What is Thaksin Shinawatra charged with?
Thailand's former leader is charged with allegedly insulting the country's royal family.
The case stems from an interview he gave to journalists in South Korea in 2015.
A complaint was later lodged by the royalist military that ousted the government of his sister, Yingluck Shinawatra.
Insulting or defaming Thailand's royal family is illegal under the country's laws, known as lèse-majesté, which are some of the strictest in the world.
The law states that it is illegal to "defame, insult or threaten the king, the queen, the heir-apparent or the regent", but there is no definition of what constitutes an insult to the monarchy.
If he is found guilty, he faces up to 15 years behind bars. He has always denied any wrongdoing.
Verapat Pariyawong said that the opinion of most in Thai legal circles was that he should be acquitted "simply because the evidence is quite thin".
"The remarks that we found did not point to the monarchy, the monarch or the king at the time," Mr Pariyawong said.
"It points to the so-called palace circles or other officials surrounding the palace. So I think that would be the turning point for the court to consider."
The court will hand down its verdict on Friday, but it is not the only case of concern for Mr Shinawatra.
He was previously convicted of conflict of interest and abuse of power, but avoided prison time by fleeing abroad in 2008.
Upon his return to Thailand in 2023, he served a brief sentence in a comfortable hospital suite before being paroled and pardoned.
A separate court will decide next month if that detention meant his sentence was not fully served.
How will the cases impact Thai politics?
If the Constitutional Court rules that she should be removed from office, Paetongtarn Shinawatra will become the third member of her family to be ousted from the role.
Her father and aunt were both ousted in military coups.
Despite being ousted, Thaksin Shinawatra has remained a powerful backroom driver of the government and Pheu Thai Party.
Law professor at Thammasat University Prinya Thaewanarumitkul said unfavourable verdicts would likely reduce the family's bargaining power and lead to an earlier-than-scheduled election.
"A new election will definitely take place by mid-2026 or maybe sooner," Professor Thaewanarumitkul said.
"The chances of Pheu Thai regaining the popular vote in the next election are very unlikely."
A spokesperson for the Pheu Thai-led government declined to comment on the upcoming court rulings.
Political science expert at Burapha University, Olarn Thinbangtieo, said Mr Thaksin would still have the support of the conservative establishment, even if he did receive unfavourable verdicts.
He said that would be because the group wanted to keep the progressive opposition at bay.
