It remains unclear why the protocol was changed after its public adoption; unofficially, it was suggested that the Church may have wanted to reduce the amount of Shroud material to be removed.

In the end, a compromise solution was reached with the so-called "Turin protocol", that discarding the blind-test method would expose the results - whatever they may be - to suspicion of unreliability.

group initially planned to conduct a range of different studies on the cloth, including radio-carbon dating. The six labs that showed interest in performing the procedure fell into two categories, according to the method they utilised: In 1982, the S. The labs were also each given three control samples (one more than those originally stated), that were: This "leak", along with the violations to the protocol, marred the credibility of this phase of the procedure and fed suspicions of tampering.

Gove consulted numerous laboratories which were able at the time (1982) to carbon-date small fabric samples. The unused half was preserved in a sealed container, in case of future need.

that radio-carbon testing dated the shroud to a date of 1260-1390 CE, with 95% confidence.This analysis itself is questioned by skeptics such as Joe Nickell, who reasons that the conclusions of the author, Raymond Rogers, result from "starting with the desired conclusion and working backward to the evidence".However, the 2008 research at the Oxford Radiocarbon Accelerator Unit may revise the 1260–1390 dating toward which it originally contributed, leading its director Christopher Ramsey to call the scientific community to probe anew the authenticity of the Shroud. group, and proposed an alternative program: Carlos Chagas Filho, neurologist and president of the Pontifical Academy of Sciences, reluctantly approved the protocol, which effectively excluded the S. A meeting with ecclesiastic authorities took place on September 29, 1986 to determine which of the two protocols would be implemented - the original proposed by S. We are faced with actual blackmail: unless we accept the conditions imposed by the laboratories, they will start a marketing campaign of accusations against the Church, which they will portray as scared of the truth and enemy of science. P group from the dating project after the sampling phase. (t)he Church must respond to the challenge of those who want it to stop the process, who would want us to show that the Church fears the science.
