This website's aim is to give researchers and other interested parties access to and information on the guidelines, ethics codes and laws that regulate and place ethical demands on the research process. 

Target audience

CODEX addresses first and foremost those who are actively involved in research, but also the interested public. Thus, no special previous knowledge is needed to understand the website's contents.


CODEX's ambition is to provide access to and information on central guidelines, ethics codes and laws that regulate and place ethical demands on the research process.

The selection of guidelines and rules was made bearing in mind research work in Sweden. We have chosen some documents that regulate or are directed toward Swedish circumstances, and some international documents with relevance to work here. When multiple-language versions of a document have been available, the Swedish version has, where appropriate, been chosen for the Swedish version of the website. There is also an english language version of CODEX.

Note that, concerning documents on ethical questions, it is not only the current 'valid' guidelines that are of interest. A researcher him/herself must always take an independent stand on various requirements and views. There is nothing to hinder an appeal from the '80s from being seen by an individual as morally imperative - even if it is not legally imperative or even if it means, for example, abstaining from a procedure that is allowed by law. Therefore, certain older policy documents have also been included when deemed appropriate.


CODEX's ambition is to provide access to and information on central guidelines, ethics codes and laws that regulate and place ethical demands on the research process. We wish to stress, however, that CODEX does not claim to be comprehensive, and furthermore that laws and regulations change frequently. Our ambition is always to keep the website as updated as possible, however we cannot guarantee accuracy in every individual piece of information.

The editor of CODEX is the sole responsible for the selection of links, and for viewpoints and opinions stated in the reserach ethics summaries. For the contents of websites linked to by CODEX, the websites in question are responsible. This is in particular true of the RSS-news provided which we have no control over. Note that we do not censor viewpoints or arguments put forth in various policy documents and ethical appeals.

Since the information presented on the website is general, it should not be used as the only source in making decisions on important matters. Although we aim to present high-quality content on our website, it is not possible to completely avoid errors. If the content linked to or paraphrased in CODEX differ from the written version of any document, the written version is authoritative.
