Austria's powerful Constitutional Court has demanded detailed data from the country's Health Ministry justifying the government's coronavirus response.
The 14-member court issued 10 sets of questions to the Health Ministry on January 26 in order to prepare for a "possible oral hearing" into a number of complaints it has received against Austria's Covid-19 measures.
The Health Ministry has until February 18 to respond.
Austria plans to ease some restrictions from Tuesday as its nationwide vaccine mandate, the first in Europe, comes into effect.
But in order to justify his government's heavy-handed rules, the court has asked Health Minister Wolfgang Mückstein to provide data across a broad range of topics including hospitalisations and deaths "with" as opposed to "from" Covid-19, the efficacy of masks and vaccines, and evidence supporting the now-rescinded "lockdown for the unvaccinated".

"The 'lockdown for the unvaccinated' is likely to be based, among other things, on the consideration that persons without Covid vaccination have a higher risk of hospitalisation than vaccinated persons, which is likely to entail a higher risk for the healthcare system," the court wrote.
"What is the effect of the 'lockdown for the unvaccinated on the hospital burden, expressed in percentages?"
Two days after the letter was sent, Austria lifted the measure.
"We came to the conclusion that the lockdown for unvaccinated people in Austria is only justifiable in the event of the threat of an imminent overburdening of intensive-care capacity," Mückstein said at a press conference.
Austrian newspaper Österreich described the pointed questions from the court, laid out in a five-page letter, as "explosive".
"The main focus is on the burden on the health system, to which the measures were linked," the paper wrote.
"(The court) is interested in whether there was ever a threat of the health system being overloaded – a scenario that, according to the law, only justifies a lockdown."
The letter began by citing a media report from October last year which stated that, as an example, patients in intensive care due to kidney failure who "happen to test positive" for Covid-19 "would count as Corona cases".
"The Constitutional Court therefore requests information as to whether the hospitalisation or death numbers given … include all persons infected with SARS-CoV-2 who are hospitalised in normal or intensive care units or who have died 'of or with' SARS-CoV-2? If so, why is this method of counting chosen?" the letter said.
The court asked for information on which virus variants were associated with these numbers, a breakdown by age cohort, and for "percentage allocation" outlining where infections occurred, such as family, work, shopping or leisure activities.
Another question asked, "By what factor does wearing an FFP2 mask indoors or outdoors reduce the risk of infection or transmission?"
A number of other questions related to vaccines, with the court requesting data on their efficacy in reducing severe illness, preventing transmission, and the durability of protection.
"By what factor does Covid vaccination reduce the risk of severe disease?" the court wrote.
"In media reports, there was talk of up to 95 per cent. Now, the general risk of dying from Covid-19 (not differentiated by age and health status) currently appears to be 0.1516 per cent.
"What does a stated vaccination efficacy of, for example, 95 per cent refer to? What do absolute and relative risk reduction mean in this context?"
The letter also requested the Covid-related hospitalisation risk over a one-year period for an unvaccinated 25-year-old compared with a double-vaccinated 25-year-old, and the same for a 65-year-old.
It concluded with a question about Austria's excess mortality statistics.
In December, the Der Standard newspaper reported that there were one-third fewer Covid-19 deaths in 2021 compared with the previous year, but that weekly excess mortality was higher.
"Is this true?" the letter asked. "If so, what was the total excess mortality in 2021 that could not be explained by Covid-19 deaths, and what is the explanation for this excess mortality?"
Austria has seen record high case numbers in recent days, fuelled by the Omicron variant.
Chancellor Karl Nehammer announced at a press conference on Saturday that starting on February 5, restaurants would be allowed to open until midnight, instead of 10pm.
Meanwhile, rules barring unvaccinated people from stores and restaurants will be phased out starting from February 12.
Austria recorded 34,748 new cases on Friday, but Nehammer said low hospitalisation rates meant rules could begin to be eased.
Officials expect Austria's Omicron wave to peak in the first week of February.
It comes as a number of countries across Europe begin a major easing of restrictions.
